Randomized Controlled TrialThe effect of patient-controlled intravenous analgesia on postoperative hypokalemia in patients undergoing laparoscopic cholecystectomy.
We investigated whether hypokalemia developed during the postoperative period and whether the use of intravenous patient-controlled analgesia (IV-PCA) could decrease the incidence of postoperative hypokalemia in patients who underwent laparoscopic cholecystectomy. ⋯ The results show that hypokalemia developed during the perioperative period and the use of IV-PCA in patients undergoing laparoscopic cholecystectomy effectively decreased the degree and incidence of postoperative hypokalemia on the day of the operation and postoperative day one.

Case ReportsA new modification for safer submental orotracheal intubation.
In patients in whom a tracheal tube cannot be inserted through the nostrils due to multiple facial trauma or hypoplasty of the nose, submental orotracheal intubation (SOI) is performed to avoid tracheostomy. We report a new modification for SOI to minimize the risk of apnea. A 20-year-old man was scheduled for sagittal split ramus osteotomy. ⋯ A second tube that had been confirmed, in advance, to snugly fit into the proximal end of the first tube was passed into the submental tunnel via a polypropylene cylinder and connected between the first tube and the breathing circuit. After careful withdrawal of the second tube through the submental tunnel, the first tube was directly connected to the breathing circuit after removal of the second tube. Although this technique requires additional time, apnea time is minimal even in patients in whom withdrawal of the tracheal tube through the submental tunnel takes time, because the second tube forms a link between the first tube and the breathing circuit, making it possible to ventilate the patient throughout the procedure.

Randomized Controlled TrialComparison of postoperative pharyngeal morbidity using the Macintosh laryngoscope or AirWay Scope after mastectomy.
We compared the characteristics of postoperative pharyngeal morbidity in intubation between the AirWay Scope (AWS) and Macintosh laryngoscope in 68 ASA I-II female patients aged 35-77 years in a randomized, double-blinded, controlled fashion. After induction of general anesthesia, the patient's trachea was intubated using the AWS or Macintosh laryngoscope by five anesthesiologists. Before leaving the operating room, postoperative sore throat, hoarseness, and dysphagia were assessed, and oral bleeding was evaluated by observation of the extubated tracheal tube. ⋯ Incidence of oral bleeding with the AWS (6.1%) was significantly lower than that with the Macintosh laryngoscope (23.5%). Pharyngeal morbidity on the day after surgery did not differ between groups, and no patient complained of delayed oral intake. In female patients, the AWS successfully reduced the incidence and severity of sore throat on the day of surgery in comparison with the Macintosh laryngoscope.
