Aids for facilitation of difficult tracheal intubation review and recent advances.

Management of difficult tracheal intubation has been facilitated by different techniques which include the use of stylets, introducers, intubating laryngeal mask airway, as well as by the development of special laryngoscope blades and fiberoptic laryngoscopes. The most recent advances for facilitation of difficult tracheal intubation is the introduction of the video-assisted laryngoscopes. The management of difficult tracheal intubation by video-assisted laryngoscopy can be further facilitated by using suspension laryngoscopy which frees the hands of the anesthesiologist to handle the insertion of the endotracheal tube with the aid of an endotracheal tube introducer, and a curved pipe stylet, under an umbrella of pharyngeal oxygen insufflation.

Induced hypocapnia is effective in treating pulmonary hypertension following mitral valve replacement.

Background: Mitral valve stenosis is often associated with increased pulmonary vascular resistance resulting in pulmonary hypertension, which may lead to or exacerbate right heart dysfunction. Hypocapnia is a known pulmonary vasodilator. The purpose of this study was to evaluate whether induced hypocapnia is an effective treatment for pulmonary hypertension following elective mitral valve replacement in adults.

Multilevel nerve stimulator-guided paravertebral block as a sole anesthetic technique for breast cancer surgery in morbidly obese patients.

In this case series, we present the effectiveness of multilevel nerve stimulator-guided paravertebral block (PVB) technique in obese women of body mass index ≥30 kg/m(2) undergoing breast cancer surgery with or without axillary dissection. Twenty-six obese women were included in this case series. Block classification, hemodynamics and complication rate, postoperative nausea and vomiting, postoperative analgesic consumption, post-anesthesia care unit (PACU) stay, and hospital stay were recorded.

Dexamethasone with either granisetron or ondansetron for postoperative nausea and vomiting in laparoscopic surgery.

In a prospective randomized double-blind study, we compared the effectiveness of dexamethasone 8 mg with either granisetron 1 mg or ondansetron 4 mg in the prevention of postoperative nausea and vomiting in patients undergoing laparoscopic surgery. Hundred ASA I and II patients scheduled for laparoscopic surgery were enrolled in the study and 84 patients completed it. Following induction of anesthesia, group I (n=42) received granisetron 1 mg and dexamethasone 8 mg, group II (n=42) received ondansetron 4 mg and dexamethasone 8 mg.
