Prophylactic ondansetron eight milligrams versus four milligrams against post spinal anaesthesia shivering

Background: Shivering is one of the commonly encountered adverse affect after spinal anaesthesia. Shivering can be very discomforting to the patient and hampers operative maneuvering. Pharmacological therapies have been studied for control and management of shivering. One such drug is ondansetron, a 5-HT3 antagonist. Aim of current study is to evaluate the efficacy of prophylactic administration of ondansetron 8 mg vs. 4 mg for prevention of shivering.Methods: A prospective, randomized, and double blind study was conducted on 100 patients, from either gender, aged 20-60 years, of the American society of anesthesiologists grade I or II, scheduled for various surgeries under spinal anesthesia. The patients were randomly divided into two groups of 50 each to receive either ondansetron 8 mg (group E) or ondansetron 4 mg, (group F) as slow intravenous infusion prior to spinal anesthesia. The primary end point were intraoperative shivering and secondary outcomes included hypotension, adverse reaction, cardiac dysrhythmia’s.Results: A total of 10 patients in group E (20%) and 20 (40%) patients in group F experienced shivering (p=0.029). Incidence of nausea was similar in both groups, total of 8 (16%) patients in group E and 5 (10%) in group B had hypotension (p=0.27). 1 (2%) patient in group E experienced bradycardia.Conclusions: Prophylactic administration of ondansetron 8 mg has better efficacy in prevention of spinal anaesthesia induced shivering with minimal side effects as compared to 4 mg dosage.

Background: Bupivacaine being the drug of choice for spinal anaesthesia is associated with serious cardiac toxicity. Levobupivacaine and ropivacaine, both being the two S enantiomers of bupivacaine can be a safer alternatives with better cardiovascular safety. Hence, the clinical efficacy of both were assessed and compared in patients undergoing spinal anesthesia.Methods: A prospective randomized controlled double blind study was done in 68 adult posted for elective lower abdominal and lower limb surgeries under spinal anesthesia. They were randomized into 2 groups. About 3ml isobaric levobupivacaine 0.5% (15mg) was given in group A and 3ml isobaric ropivacaine 0.5% (15mg) was given in group B. Onset, duration of sensory and motor blocks, time for maximum sensory and motor block, time for 2 segment sensory regression and haemodynamic parameters were recorded and analyzed.Results: All patients achieved a sensory block of T10 dermatome. Onset of sensory blockade at T10 was similar in both groups, group A (5.71±1.31min) and group B (5.94±1.72min). Time from injection to two dermatomal regression was 129.68±15.54min in group A and 111.38±22.35min in group B. Onset of Bromage score of 1 in group A was 4.68±1.27min and in group B was 6.44±1.64min. The mean duration of motor and complete motor block was prolonged in group A patients (197.74±18.51min, 168.82±17.90 min) as compared to group B (131.88±20.41min, 106.71±10.85min).Conclusions: Isobaric levobupivacaine was found to be a better and safer substitute for spinal anesthesia in patients undergoing prolonged lower abdominal and lower limb surgeries.

Objective This study was performed to determine the effects of scalp blocks with bupivacaine versus levobupivacaine on the haemodynamic response during craniotomy and the efficacies and analgesic requirements of these drugs postoperatively. Methods This randomized, prospective, placebo-controlled, double-blind study included 90 patients (age, 18–85 years; American Society of Anesthesiologists physical status, I or II). The patients were randomly divided into three groups: those who received 20 mL of 0.5% bupivacaine (Group B, n = 30), 20 mL of 0.5% levobupivacaine (Group L, n = 30), or saline as a placebo (Group C, n = 30). Scalp blocks were performed 5 min before head pinning. The primary outcome was the mean arterial pressure (MAP), and the secondary outcomes were the heart rate (HR), visual analogue scale (VAS) scores, and additional intraoperative and postoperative drug use. Postoperative pain was evaluated using a 10-cm VAS. Results During head pinning and incision, the MAP and HR were significantly higher in Group C. The additional drug requirement for intraoperative hypertension and tachycardia was significantly higher in Group C. There were no significant differences in MAP, HR, or VAS scores between Groups B and L. Conclusion Both bupivacaine and levobupivacaine can be effectively and safely used for scalp blocks to control haemodynamic responses and postoperative pain.

Background and Aims: Gabapentin and pregabalin, by decreasing noxious stimulus induced excitatory neurotransmitter release at central nervous system, may attenuate central sensitization and eventually decrease development of postoperative pain. We evaluated preemptive analgesic efficacy of single dose of oral gabapentin 600 mg and pregabalin 75mg for postoperative pain in patients undergoing lower limb orthopedic surgery under spinal anesthesia. Material and methods: A prospective, randomized, double blind study was conducted on 70 patients aged between 18 to 60 years with ASA grade 1 and 2 posted for lower limb surgeries under spinal anaesthesia. Patients were allocated into Group A and Group B receiving oral gabapentin(600mg) and oral pregabalin (75mg) respectively 1.5 hours before surgery. Primary objective was assessing duration and quality of analgesia by Visual Analogue Scale (VAS) score at 2,4,6,8,10,12,16,20 and 24 hours.Secondary objective was to assess total dose of rescue analgesic in first 24 hours, perioperative hemodynamic change and various side effects. Statistical Analysis used: Categorical data was compared using Chi- square test. Quantitative parametric data was analysed using unpaired student t-test. P value < 0.05 was considered statistically significant. Results: Mean duration of analgesia in Group A (10.53 ± 2.686 hours) was longer than Group B (7.943±3.199hr) (P = 0.0006).Mean number of analgesic dosesrequired in first 24 hourswere less in Group A (1.429 ± 0.5021) ascompared to Group B (1.771±0.6897) (P = 0.0202).All patients remained hemodynamically stable with no significant side effects noted in either group. Conclusion: We conclude that preemptive analgesic efficacy of oral gabapentin 600mg is better in comparison to oral pregabalin 75 mg for patients posted for lower limb orthopedic surgeries under spinal anesthesia.

Mean Time

A prospective double-blind study was conducted to compare the anti-emetic efficacy of ondansetron and droperidol in preventing postoperative emesis following strabismus surgery. A sample size of 213 patients was divided into three equal groups to receive ondansetron 150 μg/kg (Group A), ondansetron 75 μg/kg (Group B), or droperidol 75 fig/kg (Group C). All patients received a standardized anaesthetic technique. All episodes of emesis, recovery time, and time to tolerating oral fluids were recorded. The incidence of emesis during 24 hours was Groups A and B 19.7%, and Group C 28.2%. The lower incidence of emesis recorded by the ondansetron groups compared with the droperidol group was not statistically significant. Ondansetron at 75 μg/kg was as effective as 150 μg/kg in reducing emesis when compared with droperidol. Mean time to discharge from the recovery room was 75.3 minutes (Group A), 44.4 minutes (Group B), and 41.0 minutes (Group C). The mean time to tolerating oral fluids was 356.5 minutes (Group A), 402.8 minutes (Group B), and 378.1 minutes (Group C). There was no statistical difference in discharge times from recovery or time to tolerating oral fluids in any of the three groups.

Background: Propofol is an intravenous (IV) anesthetic agent, can irritate the skin, mucous membrane and venous intima. The main drawback is the pain at injection site following its intravenous injection. Objectives: This study was performed to evaluate the effect of intravenous nitroglycerine on pain in patients following propofol injection. Materials and Methods: Eighty adult patients of both sexes, aged 20-50 years, according to American Society of Anesthesiologists (ASA) physical status were divided into two equal groups (n=40) to receive 200 mcg intravenous nitroglycerine diluted in 10 ml saline (group A) and 10 ml normal saline as placebo (group B) at an ambient operating room temperature in a randomized and double blinded fashion to compare the pain-relieving effects of the drugs during propofol injection before the patients lost consciousness. The pain on propofol injection was assessed according to the Mc Crirrick and Hunter scale. Results: The overall incidence and severity of pain were significantly less in Groups A (nitroglycerine group) than group B (placebo group) (p< 0.05). The incidence of mild and moderate pain in Group A versus group B was 25% vs 45% and 15% vs 30% respectively (p<0.05). The incidence of score '0' (no pain) was higher in Group A (60%) than Group B (25%) (p<0.05). Conclusion: Pretreatment with 200 mcg nitroglycerine with venous occlusion for one minute is effective pretreatment in alleviating propofol injection pain when compared to placebo.

Introduction: Neuraxial opioids are widely used as adjuvants to local anaesthetic as they improve quality and duration of block. Neuraxial opioids like Butorphanol and Fentanyl allow prolonged analgesia in the postoperative period and faster recovery from spinal anaesthesia. Aim: To compare the safety and efficacy of Butorphanol and Fentanyl combined with bupivacaine for spinal anaesthesia in infraumbilical surgeries. Materials and Methods: The present study was a randomised controlled trial in which 110, ASA I and II patients of either sex who underwent elective infraumbilical surgeries under spinal anaesthesia were selected. Patients were allocated randomly into two groups A (n=55) and B (n=55). Group A (F) received intrathecal 0.5% hyperbaric bupivacaine 12.5 mg (3 mL) with fentanyl 25 microgram (0.5 mL) to make it total 3.5 mL. Group B (B) received intrathecal 0.5% hyperbaric bupivacaine 12.5 mg (3 mL) with butorphanol 250 microgram (0.25 mL) and Normal Saline (NS) 0.25 mL to make it total 3.5 mL. Heart Rate (HR), Systolic and Diastolic Blood Pressure (SBP, DBP), two segment regression time of sensory block, motor block were assessed at preset intervals. Chi-square test or Fischer’s-exact test were used and a p-value ≤0.05 was considered as statistically significant. Results: Mean of two segment sensory regression time of Group A was 41.94±1.73 minutes and Group B was 50.56±4.43 minutes (p<0.0001). Time to onset of motor block in Group A was 5.28±.32 minutes and Group B was 5.27±.32 minutes (p=0.96). Mean duration of motor block in Group A was 81.23±4.87 minutes and Group B was 109.83±2.61 minutes (p<0.0001). Time to rescue analgesic was 289.27±7.37 minutes in Group A and 378.41±10.25 minutes in Group B (p<0.0001). HR, SBP and DBP were comparable among the groups. Conclusion: Intrathecal bupivacaine-butorphanol mixture was clinically better as it provided longer duration of analgesia with lesser incidences of pruritus and nausea/vomiting compared to intrathecal fentanyl-bupivacaine mixture.

Background Recent evidence suggests that transient neurologic symptoms (TNSs) frequently follow lidocaine spinal anesthesia but are infrequent with bupivacaine. However, identification of a short-acting local anesthetic to substitute for lidocaine for brief surgical procedures remains an important goal. Prilocaine is an amide local anesthetic with a duration of action similar to that of lidocaine. Accordingly, the present, prospective double-blind study compares prilocaine with lidocaine and bupivacaine with respect to duration of action and relative risk of TNSs. Methods Ninety patients classified as American Society of Anesthesiologists physical status I or II who were scheduled for short gynecologic procedures under spinal anesthesia were randomly allocated to receive 2.5 ml 2% lidocaine in 7.5% glucose, 2% prilocaine in 7.5% glucose, or 0.5% bupivacaine in 7.5% glucose. All solutions were provided in blinded vials by the hospital pharmacy. Details of spinal puncture, extension and regression of spinal block, and the times to reach discharge criteria were noted. In the evening of postoperative day 1, patients were evaluated for TNSs by a physician unaware of the drug administered and the details of the anesthetic procedure. Results Nine of 30 patients receiving lidocaine experienced TNSs, 1 of 30 patients receiving prilocaine (P = 0.03) had them, and none of 30 patients receiving bupivacaine had TNSs. Times to ambulate and to void were similar after lidocaine and prilocaine (150 vs. 165 min and 238 vs. 253 min, respectively) but prolonged after bupivacaine (200 and 299 min, respectively; P < 0.05). Conclusions Prilocaine may be preferable to lidocaine for short surgical procedures because it has a similar duration of action but a lower incidence of TNSs.

Abstract Background: Complications with IV patient-controlled analgesia include programming errors, invasive access, and impairment of mobility. This study evaluated an investigational sufentanil sublingual tablet system (SSTS) for the management of pain after knee or hip arthroplasty. Methods: This prospective, randomized, parallel-arm, double-blind study randomized postoperative patients at 34 U.S. sites to receive SSTS 15 μg (n = 315) or an identical placebo system (n = 104) and pain scores were recorded for up to 72 h. Adult patients with American Society of Anesthesiologists status 1 to 3 after primary total unilateral knee or hip replacement under general anesthesia or with spinal anesthesia that did not include intrathecal opioids were eligible. Patients were excluded if they were opioid tolerant. The primary endpoint was the time-weighted summed pain intensity difference to baseline over 48 h. Secondary endpoints included total pain relief, patient and healthcare professional global assessments, and patient and nurse ease-of-care questionnaires. Results: Summed pain intensity difference (standard error) was higher (better) in the SSTS group compared with placebo (76 [7] vs. −11 [11], difference 88 [95% CI, 66 to 109]; P < 0.001). In the SSTS group, more patients and nurses responded “good” or “excellent” on the global assessments compared with placebo (P < 0.001). Patient and nurse ease-of-care ratings for the system were high in both groups. There was a higher incidence of nausea and pruritus in the SSTS group. Conclusion: SSTS could be an effective patient-controlled pain management modality in patients after major orthopedic surgery and is easy to use by both patients and healthcare professionals.

Background Although it has been suggested that the dilution of 5% hyperbaric lidocaine before injection for spinal anesthesia may decrease the incidence of transient neurologic symptoms, previous studies have not noted a decreased incidence between 5% and 2% lidocaine. The aim of the current study was to determine whether the incidence of transient neurologic symptoms could be altered by further diluting spinal lidocaine from 2.0% to 0.5%. Methods One hundred nine patients with American Society of Anesthesiologists physical status 1 or 2 undergoing outpatient knee arthroscopy were randomized in a double-blind fashion to receive 50 mg hyperbaric spinal lidocaine as a 2.0%, 1.0%, or 0.5% concentration. On the third postoperative day, patients were contacted by a blinded investigator and questioned regarding the incidence of postoperative complications, including transient neurologic symptoms, defined as pain or dysthesia in one or both buttocks or legs occurring within 24 h of surgery. Results The incidence of transient neurologic symptoms did not differ among patients receiving 2.0% (incidence of 15.8%), 1.0% (incidence of 22.2%), and 0.5% (incidence of 17.1%) lidocaine (P = 0.756). Conclusions For ambulatory patients undergoing arthroscopy, the incidence of transient neurologic symptoms is not reduced by decreasing spinal lidocaine concentrations from 2.0% to 1.0% or 0.5%. The incidences of transient neurologic symptoms with the 0.5%, 1.0%, and 2.0% solutions are similar to previously reported incidences for 5.0% lidocaine, suggesting that dilution of lidocaine from 5.0% to 0.5% does not change the incidence of these symptoms.
