Anesthesia, essays and researches
-
The spinal anesthesia has the definitive advantage that profound nerve block can be produced in a large part of the body by the relatively simple injection of a small amount of local anesthetic. ⋯ The addition of magnesium sulfate in the two different doses (50, 100 mg) does not affect the quality of block or duration of analgesia. However, M 100 is as effective as fentanyl as far as the duration of analgesia is concerned.

Nausea and vomiting causes distress to patients and increases surgical complications. Though various antiemetics are available, their effectiveness and fetal safety profile when used in parturient remains debatable. This randomized, double-blind, comparative study was designed with an aim to compare the antiemetic effects of ondansetron and glycopyrrolate during cesarean section. ⋯ Effect of glycopyrrolate on nausea and vomiting during cesarean section are comparable to ondansetron, but with an increased incidence of dry mouth. Glycopyrrolate has no effect on hypotension or additional analgesic requirements, but the incidence of bradycardia is significantly less.

A sustained and effective oropharyngeal sealing with supraglottic airway (SGA) is required to maintain the ventilation during laparoscopic gynecological surgery in the Trendelenburg position. This study was conducted with I-gel™ and ProSeal LMA™, two prototype SGA devices with a gastric access. ⋯ Both I-gel and PLMA are effective for ventilation in gynecological laparoscopic surgeries. However, PLMA provides better sealing as compared to I-gel.

We report a case of severe maxillofacial injury, who while undergoing later stages of reconstruction surgeries, presented with an inimitable kind of air leak during mask ventilation and its interesting management using a nasopharyngeal airway. The case also enlightens the importance of evaluating the available computed tomography images as a part of preanesthetic check-up.
