Article: The relationship between the predictors of obstructive sleep apnea and difficult intubation.[show abstract] [hide abstract]
ABSTRACT: The study was performed in order to determine the risk factors for difficult tracheal intubation in obstructive sleep apnea patients. For 115 male patients with obstructive sleep apnea syndrome and who were undergoing palatal muscle resection (PMR), we investigated the correlation between their age, height, weight, body mass index (BMI), their Epworth Sleepiness Scale (ESS), their apnea-hypopnea index (AHI), their neck circumference and the difficulty of tracheal intubation. The factors significantly related to difficult tracheal intubation in obstructive sleep apnea patients were a high AHI and a large neck circumference. There was no significant correlation between weight, BMI, arterial hypertension, ESS and difficult tracheal intubation in obstructive sleep apnea patients. In this study, a high AHI and a large neck circumference can predict difficult tracheal intubation in obstructive sleep apnea patients.Korean journal of anesthesiology 03/2011; 60(3):173-8.
Article: The effect of perioperative esmolol infusion on the postoperative nausea, vomiting and pain after laparoscopic appendectomy.[show abstract] [hide abstract]
ABSTRACT: Perioperative opioid administration results in postoperative nausea and vomiting (PONV) and acute opioid tolerance that manifests in increased postoperative pain. Esmolol is an ultra short acting cardioselective β1-adrenergic receptor antagonist, and it has been successfully used for perioperative sympatholysis and it reduces the opioid requirement during total intravenous anesthesia. We tested the hypothesis that perioperative esmolol administration results in decreased PONV and postoperative pain. Sixty patients undergoing laparoscopic appendectomy were randomly assigned to two groups (Group E and Group C). The Group E patients were administered 5-10 µg/kg/min esmolol with remifentanil that was titrated to the autonomic response. The Group C patients received normal saline that was of the same volume as the esmolol in Group E, and the remifentanil was also titrated to the vital sign. Before intubation and extubation, the Group E patients were administered 1.0 mg/kg esmolol, and the Group C patients were administered normal saline of the same volume. The incidence and severity of PONV, the pain score, the rescue antiemetics and the rescue analgesics were assessed 30 min, 6 h and 24 h after surgery. The mean arterial pressure and heart rate under anesthesia were also recorded. PONV and postoperative pain were significantly increased in Group C. These patients needed more antiemetics and analgesics in the first 24 postoperative hours. The mean arterial pressure and heart rate were significantly higher in Group C at the time of intubation and extubation. Perioperative esmolol administration contributes to the significant decrease in PONV and postoperative pain, and so this facilitates earlier discharge.Korean journal of anesthesiology 09/2010; 59(3):179-84.
