Randomized Controlled Trial Comparative Study
Effects of scalp block with bupivacaine versus levobupivacaine on haemodynamic response to head pinning and comparative efficacies in postoperative analgesia: A randomized controlled trial.
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). ⋯ 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.

Randomized Controlled Trial Comparative Study
Comparison of dexmedetomidine and propofol for conscious sedation in inguinal hernia repair: A prospective, randomized, controlled trial.
Objective The ideal agents for conscious sedation during ambulatory inguinal hernia repair are still unclear. We aimed to compare the analgesic, sedative, haemodynamic, and side effects of dexmedetomidine with those of propofol in combination with fentanyl for conscious sedation in patients undergoing inguinal hernia repair. Methods Eighty patients undergoing unilateral inguinal hernia repair were prospectively randomized to receive either dexmedetomidine (n = 40) or propofol (n = 40). ⋯ The patients' overall satisfaction score was comparable between the two groups. Conclusion Dexmedetomidine is an effective adjuvant when co-administered with fentanyl for conscious sedation in patients who undergo inguinal hernia repair. Administration of dexmedetomidine decreases the requirement of fentanyl and the pain score, but slightly prolongs the time to sedation and recovery.

Objectives To retrospectively analyse experience of radical cystectomy using spinal/epidural anaesthesia and to classify this method using the IDEAL criteria. Methods Data from patients who had undergone radical cystectomy using spinal/epidural anaesthesia were evaluated retrospectively, focusing on clinical data, intraoperative and perioperative parameters and postoperative complications. Current literature reporting on this technique was reviewed and, together with the present study, evaluated according to the IDEAL recommendations. ⋯ According to the IDEAL classification, the present study corresponds to stage 1 (idea) and overall the surgical technique can be ranked as stage 2a (development). Conclusions Radical cystectomy with epidural anaesthesia is feasible and applicable for those who are not fit for general anaesthesia. The present study confirmed the functional results of this technique, which can be classified as IDEAL stage 2a on the basis of published studies.

Objectives To determine whether age, body mass index (BMI), hand length and forearm circumference were predictive of hand grip strength in healthy Saudi Arabian adult males. Methods This cross-sectional descriptive study recruited healthy adult male volunteers. Their anthropometric characteristics including age, BMI, hand length and forearm circumference were measured using routine techniques. ⋯ Age had an inverse correlation with hand grip strength. The anthropometric measures of hand length, age and forearm circumference accounted for 44.2% (R2 0.442) of the variation of the hand grip strength. Conclusion Hand length, age and forearm circumference significantly impacted on hand grip strength in Saudi Arabian healthy adult males.

Clinical Trial
Change in pulse transit time in the lower extremity after lumbar sympathetic ganglion block: an early indicator of successful block.
Objective To investigate the change in pulse transit time (PTT)-time between the electrocardiographic R wave and the highest point of the corresponding plethysmographic wave-after lumbar sympathetic ganglion block (LSGB) and evaluate PTT as an indicator of successful LSGB. Methods Sixteen cases of sympathetically mediated lower extremity neuropathic pain treated with LSGB were studied. Correlations between the changes in PTT and temperature were used to identify the cutoff point indicating successful LSGB. ⋯ The dPTT5/PTT0 ratios of the Success and Failure groups were 6.46 ± 2.81% and 2.77 ± 1.72%, respectively. The dPTT5/PTT0 cutoff indicating successful LSGB, based on receiver operating characteristic curve analysis, was 4.23%. Conclusion PTT measurement 5 min after local anesthetic injection was an early, objective indicator of successful or failed LSGB.
