Anesthesia, essays and researches

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.

Ventral hernia is a commonly performed surgical procedure in adults. Laparoscopic intraperitoneal onlay mesh repair (IPOM) of ventral hernia is procedure of choice. IPOM of ventral hernia is associated with significant pain. Hence, our aim was to study the efficacy of instilling preemptive local analgesia for reducing postoperative pain in patients undergoing laparoscopic ventral hernia repairs. ⋯ Our study demonstrated that supplementing US-guided transversus abdominis plane (TAP) block to conventional systemic analgesics resulted in decreased VAS scores and decreased requirement of rescue analgesics. The patients ambulated early had earlier appearance of bowel sounds and decreased length of hospital stay. There was also decreased incidence of nausea and vomiting. TAP block for laparoscopic IPOM surgery significantly decreases postoperative pain and opioid requirement in patients.

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.

Clonidine, an alpha2 agonist, when added to local anesthetics in different regional and neuraxial blocks reduces the onset time, improves the efficacy, and increases the duration of postoperative analgesia. ⋯ The inclusion of 100 μg of clonidine with bupivacaine in ultrasound-guided supraclavicular brachial plexus blocks prolongs both sensory and motor blockade. It also provides significant postoperative analgesia and mild sedation which is beneficial in the immediate stressful postoperative period.
