Anesthesia, essays and researches
-
General anesthesia is preferred for clavicular surgeries. With the advent of ultrasound-guided technology, interscalene brachial plexus block with superficial cervical nerve block has become a new option for providing intraoperative anesthesia and postoperative analgesia for surgeries of the clavicle. ⋯ Ultrasound-guided interscalene brachial plexus block combined with superficial cervical nerve block is a safe and effective mode of anesthesia in comparison to general anesthesia for clavicle surgeries.

Transversus abdominis plane block (TAP) has an evolving role in postoperative analgesia following laparoscopic-assisted vaginal hysterectomy (LAVH). ⋯ The 150 μg dose of clonidine in TAP block prolongs the duration of analgesia but with higher incidence of sedation.

Perioperative shivering can occur in up to 85% of patients undergoing cesarean section under spinal anesthesia. It has many detrimental effects and disrupts early mother-child bonding. Therefore, it should ideally be prevented by either pharmacologic or nonpharmacological means. ⋯ Combined use of ondansetron and forced- air warmer was more effective in reducing the incidence of shivering in pregnant women during elective cesarean section than when used individually.

This study was designed to compare the prevention of emergence agitation (EA) of sevoflurane anesthesia by an intraoperative bolus or low-dose infusion of dexmedetomidine in pediatric patients undergoing lower abdominal surgeries. ⋯ Both bolus or low-dose infusion of dexmedetomidine was effective for the prevention of EA with sevoflurane anesthesia, but bolus dose of dexmedetomidine was more effective.

Complex gastrointestinal (GI) endoscopic procedures like endoscopic retrograde cholangiopancreatography (ERCP) require deep sedation or general anesthesia. Comorbidities with the poor physiological condition warrant endotracheal intubation to prevent hypoxia and aspiration. The gastro-laryngeal tube (GLT), a new supraglottic airway device with a separate channel for endoscope looks promising. ⋯ GLT as an airway device is a safe alternative with decreased stress response compared to endotracheal intubation for upper GI endoscopy procedures.
