Intrathecal Pethidine: An Alternative Anaesthetic for Transurethral Resection of Prostate?

We aimed to determine the usefulness of intrathecal pethidine as the sole anaesthetic for transurethral resection of prostate (TURP) while comparing the incidence of hypotension with intrathecal bupivacaine. A double-binded randomized prospective trial was conducted involving 40 patients for TURP. The patients were divided equally into two groups; group A received 2 ml 0.5% bupivacaine intrathecally and group B received 40 mg pethidine intrathecally. Changes in blood pressure and heart rate were measured over the first 30 minutes. The highest sensory block and the time to reach it were documented. The degree of motor blockade was also recorded. There was no significant difference in the incidence of hypotension. The pethidine group had significantly greater reduction in heart rate, a lower degree of motor block, shorter period before requests for postoperative analgesia but a higher incidence of sedation, nausea and vomiting. Intrathecal pethidine did not offer any advantage over intrathecal bupivacaine for TURP.

Background: Abdominal hysterectomy is often a long duration procedure and warrants intense pain relief in the post-operative period. Dexmedetomidine when added to bupivacaine in subarachnoid block prolongs the duration of surgical anaesthesia, decreases blood loss and prolongs duration of post-operative pain relief. Aims and Objective: To compare two different doses dexmedetomidine as an adjuvant to bupivacaine in sub-arachnoid block in abdominal hysterectomy surgeries. Materials and Methods: 60 patients of age group 30-60 years posted for elective abdominal hysterectomies under American Society of Anaesthesiologists (ASA) physical classification I or II were randomly allocated into 2 groups of 30 each. Group A received 5 micrograms (μg) of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Group B received 10 μg of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Changes in blood pressure, heart rate, respiratory rate, oxygen saturation, ephedrine consumption, blood loss, duration of sensory block, duration of motor block, duration of analgesia were compared between two groups. Results: There was no significant difference in change in heart rate, respiratory rate, oxygen saturation, duration of sensory block, duration of motor block between two groups. Patients in group B had significant decrease in blood pressure, blood loss and significant increase in ephedrine consumption compared to Group A. The duration of analgesia was also prolonged in group B compared to Group A. Conclusion: Dexmedetomidine in dose of 10 μg is a better adjuvant to bupivacaine for abdominal hysterectomy surgeries.Asian Journal of Medical Sciences Vol.8(2) 2017 59-63

Abstract Background Brachial plexus block has substituted general anesthesia in the majority of patients planned for upper limb surgeries as it avoids the undesired effects of the medications used in general anesthesia as well as the stress response associated with airway manipulation. Opioid agonist–antagonists such as nalbuphine are used as adjuvant to improve the anesthetic properties of bupivacaine. Verapamil has an additive effect in brachial plexus blockade in the form of decreasing the consumption of analgesics in the postoperative period with reducing onset time and extending the duration of motor and sensory blockade. The aim of this study is to investigate the adjuvant effect of verapamil versus nalbuphine to 0.5% bupivacaine in brachial plexus block as regards onset, duration of sensory and motor blockade and postoperative analgesic augmentation. The study is randomized, prospective, double-blinded, comparative study where 90 patients subjected to arm, forearm and hand surgeries were randomized into three groups, group A received 30 ml of plain bupivacaine 0.5% plus 2 ml of normal saline, group B received 30 ml of bupivacaine 0.5% plus 2 ml verapamil equivalent to 5 mg, group C received 30 ml of bupivacaine 0.5% plus 10 mg of nalbuphine diluted in 2 ml of normal saline. Results Results of this study showed that group C and group B sensory block time onset was 7.25 ± 1.5 vs. 10.92 ± 3.84 min, P < 0.001 and was shorter than that in group A (13.2 ± 2.66 min). In addition, the motor block onset was (11.10 ± 1.24 vs. 13.50 ± 3.77 min, P < 0.001) shorter than group A (17.16 ± 1.30 min). In group C and group B, sensory block duration was 396 ± 32.17 vs. 355.83 ± 18.48 min, P < 0.001, respectively and was longer than that in group A (321.13 ± 25.08 min). Also, there was prolonged motor block duration in group C and group B recording (338.92 ± 25.2 vs. 302.93 ± 15.24 min, P < 0.001) and was longer than that in group A (280.70 ± 32.35 min). Time of demand of rescue analgesia dose was significantly long in group C and group B (449.53 ± 52.45 vs. 418.13 ± 41.12 min, P < 0.001) and was longer than group A (361.31 ± 21.42 min). Both verapamil and nalbuphine have additive effect to bupivacaine improving the all anesthetic parameters of the block. Conclusion Both drugs produce favorable enhancement of time onset and effective prolongation of duration of sensory and motor blockade and extend the period of postoperative analgesia with superiority to nalbuphine over verapamil.

Objectives: The main goal of this research was to determine the differences between the values of intraocular pressure (IOP) in the supine and sitting positions, and to assess the effect of age and cardiovascular parameters. Methods: Seventy-two healthy adults were enrolled and classified into age groups: 20–30 years (group A), 31–40 years (group B), and 41–71 years (group C). Corneal biometry and cardiovascular parameters, such as heart rate (HR), were measured. IOP measurements were taken in the sitting position (IOPS) and in the supine position (IOPL) using the iCare® Pro tonometer. Results: A significant difference between the IOPS and IOPL in the entire cohort was found ( p < 0.001). Regarding the age subgroups, a significant difference ( p < 0.001) between the IOPS and IOPL was obtained in group A (2.6 ± 1.6 mmHg) and group C (1.5 ± 1.3 mmHg). There were no significant differences in the IOPS between groups. The highest IOP values were obtained for group A. The correlations between HR and IOPS are statistically significant for group A and group B, and for HR and IOPL-S for group B only. Multivariate analysis showed that HR has a significant influence on the difference in IOP in the two body positions. Conclusion: A statistically significant difference between the effect of age and the values of IOPS and IOPL was shown. Cardiovascular parameters showed some relevant statistical dependencies, but with a rather marginal significance in young people. The influence of body position for the measurement of IOP for healthy subjects does not seem to matter, despite the fact that there are some dependencies that are statistically significant.

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: Regional anesthesia techniques for gynecological procedures are on increasing trends due to their advantage of postoperative analgesia owing to intrathecal adjuvants. The present study was aimed to comparatively evaluate the clinical efficacy of clonidine with nalbuphine when co-administered intrathecally with 0.5% hyperbaric bupivacaine for Lower abdominal surgeries in Gynecology. Methods: With institutional ethics committee clearance No. 193MC/EC/2018, randomized, double blind study was conducted. After obtaining informed written consent total of 84 patients scheduled for lower abdominal surgeries were randomly allocated into two groups: Group A (n=42) - Inj. 3.5 ml Bupivacaine 0.5% + 0.2 ml Clonidine(30µg) intrathecally. Group B (n=42) - Inj.3.5 ml Bupivacaine 0.5%+0.2 ml Nalbuphine(2mg) intrathecally. The characteristics of sensory and motor block, hemodynamic data, side effects were recorded. Results: The onset of sensory block was earlier in Group B than Group A (3.08±0.52 min vs 4.00±0.54 min, p<0.001 ). The onset of motor block was also earlier in Group B than Group A (7.78±0.80 min vs 8.80±0.95min, p<0.001). The time to first rescue analgesia in patients receiving intrathecal clonidine was significantly delayed than patients receiving intrathecal nalbuphine (284.95 ± 12.93 min vs 211.52 ± 15.92 min, p<0.001). Introperative hemodynamic changes were comparable and none of the patient suffered from respiratory depression except very little cases of shivering which are not significant. Conclusions: Intrathecal clonidine as adjuvant to bupivacaine provided was clinically more effective than nalbuphine for prolonging the duration of analgesia for gynecological procedures.

Background: Transurethral resection of prostate (TURP) is the predominant surgical procedure for benign prostatic hypertension (BPH) but is not devoid of complications like capsular perforation, drop in Hb%, drop in Na+, residual adenoma; hence endeavors are evolving to combat such complications. A newer technique transurethral enucleation and resection of prostate (TUERP) has been devised to solve these problems. This study was designed to compare the safety and the efficacy of newer technique, TUERP with widely practiced TURP Methods: This randomized controlled trial was done at BSMMU, after getting ethical approval from the ethical review committee of the institute, from January to October, 2009. A total of 60 BPH patients were purposively enrolled in this study, after obtaining informed written consent and they were randomized as control, Group A (30 patients, underwent TURP) and experimental group, Group B (30 patients, underwent TEURP).Results: The mean preoperative Hb% level of Group A was 15.1 gm% (SD ± 0.5) and perioperative Hb% level was 13.04 gm% (SD ± 6.06). There was significant difference (P <0.05). The mean preoperative Hb% of Group B was 15.2 gm% (SD ± 0.5) and perioperative Hb% was 15.2 gm% (SD ± 0.48). There was no difference (P >0.05). The mean preoperative Na + of Group A was 140 mmol/l (SD ± 4.1) and perioperative Na+ was 126 mmol/l (SD ± 6.8). There was significant difference (P<0.01). The mean preoperative Na+ of Group B was 136 mmol/l (SD ± 4) and perioperative Na+ was 136 mmol/l (SD ± 2.70). There was no difference (P >0.05).Conclusion: TUERP eliminates drop in Hb% and Na+which are usual consequences following TURP. Thus TUERP can be advocated in the treatment of BPH as it also allows completeresection down to surgical capsule.Birdem Med J 2017; 7(3): 216-220

Background: There are clinical evidences for efficacy of dexmedetomidine as an adjuvant to local anaesthetic for peripheral nerve block, but very few published study are available on continuation of dexmedetomidine, with ropivacaine for ultrasound guided supraclavicular block. The present study has been designed to elucidate the effect of dexmedetomidine, in combination ropivacaine on various parameters.Methods: During period of 2 year and 3 months 84 patients were enrolled for this study. Patient in Group A were received 15 ml of 0.5% ropivacaine with 100 microgram one ml dexmedetomidine and Group B were received 15ml of 0.5% of ropivacaine with 1 ml of normal saline. Drug solution was prepared by same individual and was not part of study.Results: Both the group were comparable to each other regarding demography profile. The duration of sensory block 644.96±72.4 min in group A and the duration of sensory block in Group B was 731.53±131.54 min with p value 0.00354. The duration of motor block was 661.5±29.25 in group A and 559.77±29.25 in Group B with P value 0.0001. Duration of analgesia in Group A was 457.06±34.47 min and it was 345.70±38.032 min in Group B. The supplementation of intravenous opioid was required in 3 patients in Group A and 10 patients in group B with P value 0.037.Conclusions: When 100 microgram of dexmedetomidine was added as an adjuvant to ropivacaine is associated with early onset of sensory and motor block, prolongation of sensory and motor block and duration of analgesia in comparison with ropivacaine alone.
