Efficacy of transverse abdominis plane block in reduction of postoperation pain in laparoscopic cholecystectomy.
Transversus abdominis plane (TAP) block is a recently introduced regional anesthesia technique that is used for postoperative pain reduction in some abdominal surgeries. The present study evaluated the efficacy of the TAP block on the post laparoscopic cholecystectomy pain intensity and analgesic consumption. ⋯ The present study demonstrated that bilateral TAP block with 0.5% bupivacaine reduces post laparoscopic cholecystectomy pain intensity and fentanyl request and prolongs time to the first analgesic request. Adding sufentanil to the block solution reduced neither pain intensity nor fentanyl further consumption.

CommentClinical study to evaluate the role of preoperative dexmedetomidine in attenuation of hemodynamic response to direct laryngoscopy and tracheal intubation.
Dexmedetomidine, an α2 agonist, has been evaluated for its hypnotic, analgesic, and anxiolytic properties in the intraoperative period and critical care setting. However, data on the effect of dexmedetomidine on attenuation of pressor response to direct laryngoscopy and tracheal intubation are limited. We studied the effect of a single preinduction intravenous dose of dexmedetomidine of 0.5 μg/kg on hemodynamic responses to tracheal intubation, and dose requirements of anesthetics for induction and their adverse effects. ⋯ Administration of a single preinduction intravenous dose of dexmedetomidine of 0.5 μg/kg resulted in significant attenuation of the rise in the heart rate, systolic blood pressure, diastolic blood pressure, and mean blood pressure, until 5 minutes postintubation. It significantly reduced the dose requirements of propofol for induction and caused minimal side effects.

CommentUsing a modified syringe technique to adjust the intracuff pressure of a laryngeal mask airway.
Limiting the intracuff pressure of a laryngeal mask airway (LMA) to <60 cmH2O is recommended in clinical practice. This report aimed to assess the efficacy of a modified syringe technique to adjust the intracuff pressure of an LMA. In a preclinical study, commercially available 20-mL syringes were attached to the pilot balloon of LMAs with different preset intracuff pressures (40 cmH2O, 50 cmH2O, 60 cmH2O, 70 cmH2O, 80 cmH2O, 100 cmH2O, and 120 cmH2O). ⋯ The intracuff pressure was measured using a manometer after the plunger ceased moving. In the preclinical study, the intracuff pressure was always less than or close to 60 cmH2O after adjustment using this modified syringe technique. After evaluating the performance and characteristics of the syringe in the preclinical study, we concluded that the modified syringe technique may be useful for adjusting LMA intracuff pressure effectively.

Randomized Controlled TrialEffect of gabapentin pretreatment on the hemodynamic response to laryngoscopy and tracheal intubation in treated hypertensive patients.
This randomized, double-blind study was conducted to evaluate the effect of gabapentin pretreatment on the hemodynamic response to laryngoscopy and endotracheal intubation (LETI) in treated hypertensive patients undergoing surgery. ⋯ Gabapentin 800 mg in a single or double dose was equally effective in attenuating the hypertensive response to laryngoscopy and tracheal intubation in treated hypertensive patients.
