BACKGROUND We compared the accuracy and practicability of a new combined ear sensor device measuring pulse oximetry and transcutaneous carbon dioxide tension. METHODS Validation studies were done by comparing the results of the combined sensor with arterial blood gas measurements. In an observational part, monitoring data were obtained from 25 patients undergoing colonoscopy, sedated with mid...

We have investigated the effects of two techniques of clinical anaesthesia on human respiratory cilia by measuring cilia beat frequency of nasal tissue. In a randomized, controlled study, 13 patients undergoing either inhalation anaesthesia with isoflurane or total i.v. anaesthesia with propofol and alfentanil had nasal ciliated epithelial samples removed at the beginning and after 1 h of anaes...

BACKGROUND The aim of this study was to determine the clinical effective dose of rocuronium for tracheal intubation using a lightwand after induction with propofol, alfentanil, and a low concentration of sevoflurane. METHODS Twenty-eight adults scheduled to undergo elective surgery lasting less than one hour were enrolled in this study. All patients received alfentanil (10 microg/kg) and prop...

OBJECTIVES To observe the effects of both propofol/alfentanil and propofol/ketamine on sedation during upper gastrointestinal system endoscopy in morbidly obese patients (UGSEMOP). METHODS In a prospective, double-blinded, randomized clinical study, 52 patients scheduled for UGSEMOP were assigned to either group A (n=26; 10 µg/kg intravenous [IV] alfentanil) or group K (n=26; 0.5 mg/kg IV ket...

BACKGROUND/AIMS Different drug combinations are used for sedation in colonoscopy procedures. A ketamine-propofol (ketofol) mixture provides effective sedation and has minimal adverse effects. Alfentanil also provides anesthesia for short surgical procedures by incremental injection as an adjunct. However, no study has investigated the use of ketofol compared with an opioid-propofol combination ...

Intervention Surgeons (n=2) were allocated to music (20 patients) or no music (20 patients). Patients in the music group were given stereo headphones, a cassette player, and a choice of 22 types of music (including soft hits, classical guitar, chamber music, and folk music); patients listened to their selected music during the preoperative, surgical, and postoperative periods. All patients rece...
