Context: Dexmedetomidine as an adjuvant to local anesthetics in peripheral nerve blocks has been used in only a few studies. Aims: We aimed at assessing the effect of dexmedetomidine as an adjuvant to ropivacaine in supraclavicular brachial plexus block. Settings and Design: Random, controlled, and triple blind. Materials and Methods: Sixty American Society of Anesthesiologist grade I and II patients of either sex scheduled for elective upper limb surgery under supraclavicular brachial plexus block were divided into three equal groups in a prospective randomized double-blind controlled manner. For block patients in Group C received 0.5% ropivacaine (30cc), 0.5% ropivacaine with 50 μg dexmedetomidine (30cc) in Group D and 0.5% ropivacaine (30cc) in Group D-IV along with intravenous infusion of 50 μg dexmedetomidine in normal saline. Statistical Analysis Used: IBM-SPSS software version 17, Chi-square test, Mann-Whitney U-test. Results: Demographic profile and surgical characteristics were similar in all the three groups. Sensory block and motor block onset was earlier in group D than in group D-IV and group C. The sensory block and motor block duration was also prolonged in group D when compared with group D-IV and group C. The duration of analgesia was significantly longer in group D and D-IV when compared to group C. Conclusions: Dexmedetomidine as an adjuvant to 0.5%ropivacaine in ultrasound guided brachial plexus block shortens the sensory as well as motor block onset time, prolongs sensory and motor block duration and also increases the duration of analgesia. The action of dexmedetomidine most probably is local rather than centrally mediated.

Background: Preclinical and clinical data suggest the possibility of neurotoxicity following exposure of young children to general anesthetics with subsequent behavioral disturbances. The aim of the study was to determine the overall effect of repeated general anesthesia on behavior and emotions of young children aged 1½-5 years old, compared to healthy children. Materials and Methods: Thirty-five children underwent repeated anesthesia and surgery were matched with the same number of healthy children who attended vaccination clinic, as a control group. Both groups were administered the child behavior checklist (CBCL) 1½-5 years and Diagnostic and Statistical Manual of Mental Disorders (DSM) oriented scale. Behavior data were collected through a semi-structured questionnaire. Results: The CBCL score revealed that children with repeated anesthesia were at risk to become anxious or depressed (relative risk [RR]; 95% confidence interval [CI] = 11 [1.5-80.7]), to have sleep (RR; 95% CI = 4.5 [1.1-19.4]), and attention problems (RR; 95% CI = 8 [1.1-60.6]). There was no difference in the risk between the two groups regarding emotionally reactive, somatic complaints, withdrawn problems, aggressive behavior, internalizing or externalizing problems. On DSM scale, children with repeated anesthesia were at risk to develop anxiety problems (RR; 95% CI = 3.7 [1.1-12.0]), and attention deficit/hyperactivity problems (RR; 95% CI = 3 [1.1-8.4]). There was no difference in the risk between the two groups regarding affective, pervasive developmental and oppositional defiant problems. Conclusion: Young children who undergone repeated surgical procedures under general anesthesia were at risk for subsequent behavioral and emotional disturbances. Proper perioperative pain management, social support, and avoidance of unpleasant surgical experiences could minimize these untoward consequences.

Context: Hormonal and mechanical factors make obstetric patients need strict dose calculations of local anesthetics intrathecally for spinal anesthesia. Any greater dose of local anesthetics can cause hemodynamic instability, maternal morbidity and any lesser dose can produce inadequate block. Hence, we hypothesized in our study that by using low dose of bupivacaine with fentanyl can maintain stable hemodynamics and provide better analgesia. Aim: The aim was to compare the hemodynamics and duration of analgesia using a low dose (7.5 mg) bupivacaine fentanyl mixture to a conventional dose (10 mg) of hyperbaric bupivacaine for cesarean section. Settings and Design: Double-blinded, randomized, controlled prospective study was conducted at a tertiary academic hospital from 2008 to 2011. Materials and Methods: Fifty singleton parturient, scheduled for elective caesarean section were randomly allocated into two groups. Study group (group-S) received a combination of 25 μg fentanyl and 7.5 mg of hyperbaric bupivacaine, whereas the control group (group-C) received 10 mg of hyperbaric bupivacaine. Maternal hemodynamics, sensory and motor block, duration of analgesia and the Apgar score of the newborn were compared between the groups. Statistical Analysis Used: Observational descriptive statistics, statistical package for social sciences (SPSS Inc. Released 2006, SPSS for Windows, Version 15.0. Chicago), paired t-test was used as applicable. Results: The blood pressure significantly decreased with >25% fall from the baseline in group-C (98.76 ± 8.36) than in group-S (117.32 ± 12.21) with P < 0.001.The duration of effective analgesia was significantly prolonged in the study group than in the control group (P < 0.001). Conclusion: The combination of low dose bupivacaine and fentanyl in comparison to bupivacaine alone is hemodynamically stable and prolonged duration of analgesia in caesarean section.

Introduction and Aim: Middle ear surgeries can be performed under local anesthesia and sedation and can be well tolerated by the patient with minimal discomfort. This study was undertaken to compare two techniques of conscious sedation, intravenous midazolam, and propofol infusion for tympanoplasty. Materials and Methods: Forty patients scheduled for right or left tympanoplasty. American Society of Anesthesiologists I or II in age group 18-75 years were included in the study. The patients were randomly allocated into one of the two groups to receive either propofol (group I) or midazolam (group II). Results: The mean duration of anesthesia was 116.00 ± 33.94 min in group I, while 97.50 ± 30.76 min in group II (P = 0.07). The modified Ramsay sedation scale was not statistically significant in both the groups. In group I, 70% of the patients and 95% of the patients in group II had amnesia during the surgery (P = 0.091). The mean visual analog scale (VAS) score for surgeons and patients was not statistically significant in both the groups. In group I there was a positive correlation between the total dose of fentanyl and VAS score for surgeons (P = 0.02). There was also a positive correlation between the total dose of propofol and VAS score for surgeons (P = 0.034) and patients (P = 0.039) in group I. Conclusion: Though propofol had shown a faster recovery and less nausea vomiting, we need a larger sample size to conclude, which of the technique is better. Both the techniques are safe, simple and versatile and provide excellent sedation with rapid trouble free recovery.

Background: In patients with penetrating eye injury and a full stomach, suxamethonium is still used for rapid sequence induction of anesthesia. But its use is associated with the rise in intraocular pressure (IOP) and this can result in permanent vision loss in these patients. Dexmedetomidine and clonidine are two alpha-2 adrenergic agonist drugs which prevent the rise in IOP. The aim of this study is to compare the efficacy of intravenous (i.v.) dexmedetomidine and clonidine in preventing an increase in IOP after administration of suxamethonium and tracheal intubation. Materials and Methods: Sixty patients undergoing elective nonophthalmic surgery under general anesthesia were included in this clinical study. Patients were randomly assigned into three groups to receive 0.5 mcg/kg dexmedetomidine (Group D), 2 mcg/kg clonidine (Group C) or normal saline (Group S) as premedication i.v. over a period of 10 min before induction. IOP, heart rate, and mean arterial pressure were recorded before and after premedication, after suxamethonium, after intubation and then after 5 min. Results: Following administration of dexmedetomidine and clonidine IOP decreased in both groups. After suxamethonium IOP increased in all three groups but it never crossed the baseline in Group D and C. After laryngoscopy and intubation IOP again increased in all three groups but in dexmedetomidine group it never crossed the baseline whereas in clonidine group it was significantly higher than the baseline. Conclusion: Single i.v. dose of dexmedetomidine premedication (0.5 mcg/kg) blunt the IOP and hemodynamic response to suxamethonium injection and tracheal intubation more effectively than single i.v. dose of clonidine premedication (2 mcg/kg).

Background: Traditional Macintoch laryngoscopy is known to cause a rise in intraocular pressure (IOP), tachycardia and hypertension. These changes are not desirable in patients with glaucoma and open globe injury. GlideScope is a video laryngoscope that functions independent of the line of sight, reduces upward lifting forces for glottic exposure and requires less cervical neck movement for intubation, making it less stimulating than Macintosh laryngoscopy. Aim: The aim was to assess the variations in IOP and hemodynamic changes after GlideScope assisted intubation. Materials and Methods: After approval of the local Institutional Research and Ethical Board and informed patient consent, 50 adult American Society of Anesthesiologist I and II patients with normal IOP were enrolled in a prospective, randomized study for ophthalmic surgery requiring tracheal intubation. In all patients, trachea was intubated using either GlideScope or Macintoch laryngoscope. IOP of nonoperated eye, heart rate and blood pressure were measured as baseline, 1 min after induction, 1 min and 5 min after tracheal intubation. Results: IOP was not significantly different between groups before and after anesthetic induction and 5 min after tracheal intubation (P = 0.217, 0.726, and 0.110 respectively). The only significant difference in IOP was at 1 min after intubation (P = 0.041). No significant difference noted between groups in mean arterial pressure (P = 0.899, 0.62, 0.47, 0.82 respectively) and heart rate (P = 0.21, 0.72, 0.07, 0.29, respectively) at all measurements. Conclusion: GlideScope assisted tracheal intubation shown lesser rise in IOP at 1 min after intubation in comparison to Macintoch laryngoscope, suggesting that GlideScope may be preferable to Macintosh laryngoscope.

The management of pregnant patients with traumatic brain injury is challenging. A multidisciplinary team approach is mandatory, and management should be individualized according to the type and extent of injury, maternal status, gestational age, and fetal status. We report a 27-year-old term primigravida presenting after head injury with Glasgow coma scale score 11 and anisocoria. Depressed temporal bone fracture and acute epidural hematoma were diagnosed, necessitating an urgent neurosurgery. Her fetus was viable with no signs of distress and no detected placental abnormalities. Cesarean delivery was performed followed by craniotomy in the same setting under general anesthesia with good outcome of the patient and her baby.

Morquio's syndrome, also known as mucopolysaccharidosis type IV is an autosomal recessive disorder, caused by deficiency of n-acetylgalactosamine-6-sulphate. Anesthetic management of this syndrome is a great challenge, especially in pediatric age group as "cannot ventilate, cannot intubate" scenario can be encountered by anesthesiologist due to the possibility of total airway collapse. Herewith, we are reporting a case of child with Morquio's syndrome where I-gel assisted fiber-optic intubation was used for safe endotracheal intubation.

Context: Though intensive care units (ICUs) only account for 10% of hospital beds, they consume nearly 22% of hospital resources. Few definitive costing studies have been conducted in Indian settings that would help determine appropriate resource allocation. Aim: To evaluate and compare the cost of intensive care delivery between multi-specialty and neurosurgery ICU in an apex trauma care facility in India. Materials and Methods: The study was conducted in a polytrauma and neurosurgery ICU at a 203 bedded level IV trauma care facility in New Delhi, India from May, 2012 to June 2012. The study was cross-sectional, retrospective, and record-based. Traditional costing was used to arrive at the cost for both direct and indirect cost estimates. The cost centers included in study were building cost, equipment cost, human resources, materials and supplies, clinical and nonclinical support services, engineering maintenance cost, and biomedical waste management. Statistical Analysis: Fisher's two-tailed t-test. Results: Total cost/bed/day for the multi-specialty ICU was Rs. 14,976.9/- and for the neurosurgery ICU was Rs. 14,306.7/-, manpower constituting nearly half of the expenditure in both ICUs. The cost center wise and overall difference in the cost among the ICUs were statistically significant. Conclusions: Quantification of expenditure in running an ICU in a trauma center would assist healthcare decision makers in better allocation of resources. Although multi-specialty ICUs are more expensive, other factors will also play a role in defining the kind of ICU that need to be designed.

Background: Central venous cannulation (CVC) is frequently required during the management of patients with liver disease with deranged conventional coagulation parameters (CCP). Since CVC is known to be associated with vascular complications, it is standard practice to transfuse Fresh-Frozen Plasma or platelets to correct CCP. These CCP may not reflect true coagulopathy in liver disease. Additionally CVC when performed under ultrasound guidance (USG-CVC) in itself reduces the incidence of complications. Aim: To assess the safety of USG-CVC and to evaluate the incidence of complications among liver disease patients with coagulopathy. Setting and Design: An audit of all USG-CVCs was performed among adult patients with liver disease in a tertiary care center. Materials and Methods: Data was collected for all the adult patients (18-60 years) of either gender suffering from liver disease who had required USG-CVC. Univariate and multivariate regression analysis was done to identify possible risk factors for complications. Results: The mean age of the patients was 42.1 ± 11.6 years. Mean international normalized ratio was 2.17 ± 1.16 whereas median platelet count was 149.5 (range, 12-683) × 10 ⁹ /L. No major vascular or non-vascular complications were recorded in our patients. Overall incidence of minor vascular complications was 18.6%, of which 13% had significant ooze, 10.3% had hematoma formation and 4.7% had both hematoma and ooze. Arterial puncture and multiple attempts were independent risk factors for superficial hematoma formation whereas low platelet count and presence of ascites were independent risk factors for significant oozing. Conclusion: Ultrasound guidance -CVC in liver disease patients with deranged coagulation is a safe and highly successful modality.

Background: There continues to be a significant focus on the value of regional and neuraxial anesthesia techniques for adjunctive use when combined with general anesthesia. The reported advantages include decreased patient opiate exposure, decreased medication-related adverse effects, decreased postanesthesia recovery room time and hospital stay, and increased patient satisfaction. Materials and Methods: The authors present a case-controlled series evaluating the use of a single caudal epidural injection prior to incision as an adjunct to general anesthesia for the open repair of slipped capital femoral epiphysis. Opiate consumption, pain scores, and hospital stay were compared between the two cohorts of 16 adolescent patients. All patients received a demand-only patient-controlled opiate delivery system. Results: Although the failed block rate was high (31%), there was decreased opioid use in the perioperative arena as well as during the first 24 postoperative hours in patients who had a successful caudal epidural block. Furthermore, discharge home was possible in 27% of patients who received a caudal epidural block compared to 0% of patients who did not receive a caudal block. Conclusion: The potential utility of caudal epidural block as an adjunct to general anesthesia during major hip surgery in adolescents is presented. Factors resulting in a failed block in this patient population as well as the use of the ultrasound as an added modality to increase block success are reviewed.

Aim: The number of patients with end-stage renal disease (ESRD) has shown a consistent rise in India in recent years. Continuous ambulatory peritoneal dialysis (CAPD) remains one of the safe and effective forms of treatment. In this study, we have tried to assess the effectiveness of field block technique for analgesia during catheter placement surgery until 24 h postoperatively, also, if it can obviate the need for general anesthesia in these high-risk patients. Materials and Methods: We studied 52 ESRD patients from 2010 to 2012 who were posted for CAPD catheterization in the Department of Urology, Care Hospital, Hyderabad, India. Under ultrasound guidance, "unilateral posterior" and "unilateral subcostal" transversus abdominis plane block anesthesia were given for the placement of CAPD catheter. Patient's intra-operative pain and post-operative pain were recorded with visual analog scores (VAS) and analyzed. Results: All patients in our study belonged to American Society of Anesthesiologists category 2 or 3 with multiple co-morbidities. 41 out of 52 patients required no supplemental analgesia during the procedure; 8 patients needed additional infiltration of local anesthetic during skin incisions. Three patients required supplemental analgesia and were considered as failure. A VAS of two was noted in 30 patients and 1 in 19 Patients. No Patient had significant pain 24 h post operatively. No local complication was noted in any patient. Conclusion: CAPD Catheterization under regional field block remains safe and effective options for ESRD patients.

Presence of intraoral pathology poses a great challenge during management of pediatric airway. We report management of big intraoral cystic swelling physically occupying the entire oral cavity restricting access to airway. Preintubation aspiration of swelling was done to decrease its size and make room for airway manipulation, followed by laryngoscopy and intubation in lateral position. Airway patency is at risk in postoperative period also, in this case, though the swelling decreased in size postoperatively but presence of significant edema required placement of tongue stitch and modified nasopharyngeal airway. Case report highlights simple maneuvers to manage a difficult case.

Ramsay hunt syndrome ^[1] is a varicella zoster virus infection of the geniculate ganglion of the facial nerve. It is typically associated with a red rash and blister (inflamed vesicles or tiny water filled sacks in the skin) in or around the ear and eardrum and sometimes on the roof of the mouth or tongue. Corticosteroid, oral acyclovir, and anticonvulsant are used for treatment of this. In addition to this sympathetic neural blockade via stellate ganglion block is used to prevent facial nerve damage and relieve symptoms. We present a case of Ramsay hunt syndrome in which pain and symptoms are not relieved by oral medication but by daily sittings of stellate ganglion block with local anesthetic and steroid, pain, and other symptoms are relieved, and facial nerve damage is prevented.

Background: Laparoscopy though minimally invasive produces significant hemodynamic surge and neuroendocrine stress response. Though general anesthesia (GA) is the conventional technique, now-a-days, regional anesthesia has been accepted for laparoscopic diagnostic procedures, and its use is also being extended to laparoscopic surgeries. Objective: The aim was to compare the hemodynamic surge and neuroendocrine stress response during laparoscopic cholecystectomy (LC) under GA and spinal anesthesia (SA) in American Society of Anesthesiologists (ASA) PS 1 patients. Materials and Methods: Thirty ASA physical status I patients, aged 18-65 years were randomly allocated into two equal groups of 15 each. Group A received GA with controlled ventilation. Patients were preoxygenated for 5 min with 100/5 oxygen, premedicated with midazolam 0.03 mg/kg intravenous (i.v), fentanyl 2 mcg/kg i.v; induction was done with thiopentone 3-5 mg/kg i.v; intubation was achieved after muscle relaxation with 0.5 mg/kg atracurium besylate i.v. Anesthesia was maintained with 1-2% sevoflurane and N2O:O2 (60:40) and intermittent i.v injection of atracurium besylate. Group B SA with 0.5% hyperbaric bupivacaine and 25 μg fentanyl along with local anesthetic instillation in the subdiaphragmatic space. Mean arterial pressure, heart rate (HR), oxygen saturation, end tidal carbon-dioxide were recorded. Venous blood was collected for cortisol assay before induction and 30 min after pneumoperitoneum. All data were collected in Microsoft excel sheet and statistically analyzed using SPSS software version 16 (SPSS Inc., Chicago, IL, USA). All numerical data were analyzed using Student's t-test and paired t-test. Any value <0.05 was taken as significant. Results: Mean arterial pressure and mean HR and postpneumoperitoneum cortisol level were lower in group B than group A though the difference was not statistically significant in hemodynamic parameters but significant in case of cortisol. Conclusion: Spinal anesthesia administered for LC maintained comparable hemodynamics compared to GA and did not produce any ventilatory depression. It also produced less neuroendocrine stress response as seen by reduction in the level of serum cortisol in ASA PS 1 patients put for LC.

Background: Post operative recovery has been reported to be faster with desflurane than sevoflurane anesthesia in previous studies. The use of desflurane is often criticized in neurosurgery due to the concerns of cerebral vasodilation and increase in ICP and studies comparing desflurane and sevoflurane in neurosurgey are scarce. So we compared the intraoperative brain condition, hemodynamics and postoperative recovery in patients undergoing elective supratentorial craniotomy receiving either desflurane or sevoflurane. Materials and Methods: Fifty three patients between 18-60yr undergoing elective supratentorial craniotomy receiving N ₂ O and oxygen (60%:40%) and 0.8-1.2 MAC of either desflurane or sevoflurane were randomized to group S (Sevoflurane) or group D (Desflurane). Subdural intra cranial pressure (ICP) was measured and brain condition was assessed.. Emergence time, tracheal extubation time and recovery time were recorded. Cognitive behavior was evaluated with Short Orientation Memory Concentration Test (SOMCT) and neurological outcome (at the time of discharge) was assessed using Glasgow Outcome Score (GOS) between the two groups. Results: The emergence time [Group D 7.4 ± 2.7 minutes vs. Group S 7.8 ± 3.7 minutes; P = 0.65], extubation time [Group D 11.8 ± 2.8 minutes vs. Group S 12.9 ± 4.9 minutes; P = 0.28] and recovery time [Group D 16.4 ± 2.6 minutes vs. Group S 17.1 ± 4.8 minutes; P = 0.50] were comparable between the two groups. There was no difference in ICP [Group D; 9.1 ± 4.3 mmHg vs. Group S; 10.9 ± 4.2 mmHg; P = 0.14] and brain condition between the two groups. Both groups had similar post-operative complications, hospital and ICU stay and GOS. Conclusion: In patients undergoing elective supratentorial craniotomy both sevoflurane and desflurane had similar intra-operative brain condition, hemodynamics and post operative recovery profile.

Background: Several measurement tools have been used for assessment of postoperative pain in pediatric patients. Self-report methods have limitations in younger children and parent, nurse or physician assessment can be used as a surrogate measure. These tools should be tested in different cultures as pain can be influenced by sociocultural factors. The objective was to assess the inter-rater agreement on four different behavioral pain assessment scales in our local population. Materials and Methods: This prospective, descriptive, observational study was conducted in Pakistan. American Society of Anesthesiologists I and II children, 3-7 years of age, undergoing elective surgery were enrolled. Four pain assessment scales were used, Children's Hospital of Eastern Ontario Pain Scale (CHEOPS), Toddler Preschool Postoperative Pain Scale (TPPPS), objective pain scale (OPS), and Face, Legs, Activity, Cry, Consolability (FLACC). After 15 and 60 min of arrival in the postanesthesia care unit (PACU), each child evaluated his/her postoperative pain by self-reporting and was also independently assessed by the PACU nurse, PACU anesthetist and the parent. The sensitivity and specificity of the responses of the four pain assessment scales were compared to the response of the child. Results: At 15 min, sensitivity and specificity were >60% for doctors and nurses on FLACC, OPS, and CHEOPS scales and for FLACC and CHEOPS scale for the parents. Parents showed poor agreement on OPS and TPPS. At 60 min, sensitivity was poor on the OPS scale by all three observers. Nurses showed a lower specificity on FLACC tool. Parents had poor specificity on CHEOPS and rate of false negatives was high with TPPS. Conclusions: We recommend the use of FLACC scale for assessment by parents, nurses, and doctors in Pakistani children aged between 3 and 7.

Context: Acute physiology and chronic health evaluation II (APACHE II) is one of the most general classification systems of disease severity in Intensive Care Units and Glasgow Coma Score (GCS) is one of the most specific ones. Aims: The aim of the current study was to assess APACHE II and GCS ability in predicting the outcomes (survivors, non-survivors) in the Post Anesthesia Care Unit's (PACU). Settings and Design: This was an observational and prospective study of 150 consecutive patients admitted in the PACU during 6-month period. Materials and Methods: Demographic information recorded on a checklist, also information about severity of disease calculated based on APACHE II scoring system in the first admission 24 h and GCS scale. Statistical Analysis Used: Logistic regression, Hosmer-Lemeshow test and receiver operator characteristic (ROC) curves were used in statistical analysis (95% confidence interval). Results: Data analysis showed a significant statistical difference between outcomes and both APACHE II and Glasgow Coma Score (GCS) (P < 0.0001). The ROC-curve analysis suggested that the predictive ability of GCS is slightly better than APACHE II in this study. For GCS the area under the ROC curve was 86.1% (standard error [SE]: 3.8%), and for APACHE II it was 85.7% (SE: 3.5%), also the Hosmer-Lemeshow statistic revealed better calibration for GCS (χ² = 5.177, P = 0.521), than APACHE II (χ² = 10.203, P = 0.251). Conclusions: The survivors had significantly lower APACHE II and higher GCS compared with non-survivors, also GCS showed more predictive accuracy than APACHE II in prognosticating the outcomes in PACU.

Clonidine, an alpha-2-adrenergic agonist, may have a clinically relevant analgesic action but also a hypotensive action, when administered spinally. Aim: To evaluate the analgesic and circulatory effects of low-dose intrathecal clonidine co-administered with hyperbaric bupivacaine in septuagenarian patients undergoing sub-umbilical surgeries. Materials and Methods: A total of 20 patients within the age group of 70-80 years of either sex, enrolled in this study, were randomly divided into groups of 10 each. Group I received clonidine 7.5 μg as an adjuvant to 15 mg of hyperbaric bupivacaine and Group II (control group) received 15 mg of bupivacaine with saline to make volume in the two solutions equal. Result: The level of subarachnoid block was comparable in the two groups. Duration of motor blockade was longer in the clonidine group (221.4 ± 35.92 min) compared with the control group (112.3 ± 12.45 min). Request for 1 ^st dose of analgesic was earlier in the control group (135.5 ± 28.52 min) than the clonidine group (295 ± 18.85 min). Mean arterial pressure (clonidine 77.67 ± 6.47 vs. control 93.87 ± 3.03, P = 0.0002) and heart rate (clonidine 65.2 ± 5.20 vs. control 77.4 ± 6.06, P = 0.003) were significantly lower (P < 0.05) in the clonidine group compared with the control group from 20 mins after the block to the end of 3 h. In the clonidine group, 3 patients had postoperative headache, 4 had intra-operative shivering. 2 patients in the clonidine group also developed hypotension and 1 bradycardia and 1 of them developed bradyapnea along with acute hypotension 5 min after shifting to the postoperative ward and later recovered on resuscitation. In the control group 2 patients had bradycardia, 6 had intra-operative shivering and 3 had postoperative headache. Conclusion: We conclude that addition of clonidine in the dose of 7.5 μg to bupivacaine significantly increases the duration of spinal analgesia with clinically insignificant influence on hemodynamic parameters.
