The prospective, observational study was conducted on 120 patients scheduled for elective surgery requiring general anesthesia and tracheal intubation. The depth of the pre-epiglottic space (Pre-E), the distance from the epiglottis to the midpoint of the distance between the vocal cords (E-VC) was measured sonographically. Similarly, hyomental distance ratio (HMDR) was sonographically measured with head in neutral and extended positions. The primary outcome was the efficacy of Pre E/E-VC, HMDR for predicting difficult laryngoscopy (Cormack-Lehane [CL] Grade 3, 4). The secondary outcome was to correlate these parameters to CL grading. Difficult intubation was observed in 12.5% of patients. The mean ± standard deviation (SD) of Pre E/E-VC ratio was 1.33±0.335, 1.62±0.264 and 1.87±.243, 2.22±.29 for CL Grade 1, 2, 3, and 4, respectively ( = 0.00). The mean ± SD ...

However, until today, there has been no consensus as regards the ideal dose of magnesium sulfate as an adjuvant in the subarachnoid block. The present study was designed to examine whether the addition of intrathecal magnesium sulfate (50 and 100 mg) would enhance the analgesic efficacy of intrathecal bupivacaine. We hypothesized that the additive effect of magnesium sulfate as an adjuvant to bupivacaine in subarachnoid block is dose dependent. Materials and methods This study was carried out on 90 American Society of Anesthesiology I and II patients of both sexes in the age group of 20–60 years scheduled for below knee surgeries under subarachnoid block. Group 1 (n = 30) patients received intrathecal 0.5% heavy bupivacaine (2.8 ml) +0.2 ml normal saline; group 2 (n = 30) received intrathecal 0.5% heavy bupivacaine (2.8 ml) +50 mg (0.1 ml) magnesium sulfate +0.1 ml normal saline; and group 3 (n = 30) received intrathecal 0.5% heavy bupivacaine (2.8 ml)+100 mg (0.2 ml) magnesium sulfate. The primary outcome measure was the duration of postoperative analgesia, and secondary outcomes included the number of supplemental analgesic requirements, block characteristics, and hemodynamic stability. Results The onset of sensory and motor block was delayed in the magnesium group (100 mg>50 mg). There was a significant prolongation of postoperative analgesia in the magnesium group in a dose-dependent manner, and total dose of rescue analgesic requirement was found to be significantly delayed in the 100 mg group. Patients in all groups remained hemodynamically stable without any adverse effects. Conclusion Magnesium sulfate (100 mg) as an adjuvant to bupivacaine in subarachnoid block prolongs the duration of analgesia and decreases the demand for rescue analgesics compared with the control and the magnesium sulfate 50 mg group.

We aimed to compare equal doses of clonidine or dexmedetomidine as an adjuvant to levobupivacaine in FSNB for post-operative analgesia. Methods: Ninety patients scheduled to undergo below knee orthopaedic surgeries under subarachnoid block were divided into three groups: Group LL (n = 30) patients received 38 mL of 0.125% levobupivacaine with 2 mL normal saline, Group LD (n = 30) patients received 38 mL of 0.125% levobupivacaine with 0.5 μg/kg dexmedetomidine and Group LC (n = 30) received 38 mL of 0.125% levobupivacaine with 0.5 μg/kg clonidine in saline to make total drug volume of 40 mL. The primary and secondary outcome variables were duration of analgesia and rescue analgesic requirement, verbal rating score respectively. Continuous variables were analysed with analysis of variance or the Kruskal-Wallis test on the basis of data distribution. Categorical variables were analysed with the contingency table analysis and the Fisher's exact test. Results: Duration of analgesia was prolonged with dexmedetomidine (10.17 ± 2.40 h) and clonidine (7.31 ± 1.76 h) as compared to control (4.16 ± 1.04 h, P = 0.00). Significantly lower pain scores were observed in dexmedetomidine group as compared to clonidine up to 8 h post-operatively. Conclusion: Equal doses of clonidine or dexmedetomidine added to levobupivacaine prolonged the duration of analgesia, decreased requirement of rescue analgesia. Dexmedetomidine delays the requirement of rescue analgesics with better pain scores as compared to clonidine.

Material and Methods: A prospective, randomized, controlled, double-blind study was undertaken in patients scheduled for upper limb surgeries under supraclavicular block. All the three group patients received either of the following drugs mixtures: Group Abupivacaine 0.5%-18 ml + normal saline-7 ml for block and normal saline-10 ml intravenously. Group B-bupivacaine 0.5%-18 ml + normal saline-7 ml mixture for block and tramadol (100 mg) diluted to10 ml-intravenously. Group C-bupivacaine 0.5%-18 ml + tramadol (100 mg) + normal saline-5 ml mixture and normal saline 10 ml intravenously. The patients were observed for sensory, motor onset along with the duration of sensory and motor block. Patients were monitored for sedation and hemodynamic parameters during intra-operative and postoperative period. Pain-free period and demand for rescue analgesia was noted in all the patients. Results: The study demonstrates that the mixture of tramadol and bupivacaine injected perineurally for supraclavicular brachial plexus block hastens the onset of sensory block, motor block and provides a longer duration of motor blockade and demand for rescue analgesia as compared to other two groups. Conclusions: In conclusion, the addition of tramadol to bupivacaine mixtures as an adjunct for supraclavicular brachial plexus block provide better postoperative analgesia for orthopedic upper extremity surgery in comparison to control or systemic tramadol group without any side effects.
