Comparison of midazolam, propofol and fentanyl combinations for sedation and hemodynamic parameters in cataract extraction.

Objective: Midazolam, propofol and fentanyl were compared in terms of sedation during cataract extraction. Hemodynamic parameters, sedation level, postoperative satisfaction, and side effects were investigated.

Methods: The study was carried out in Hacettepe University Hospitals Ophthalmology Operating Theatres in 2005.

The effect of premedication on preoperative anxiety.

The aim of this study was to evaluate the effect of premedication on anxiety, cortisol, residual gastric volume and gastric pH. Following the approval of the institutional Clinical Research Ethics Committee, 100 patients in ASA I-II scheduled for elective gynecologic surgery, were included into a double blind study.

Infusion and bolus administration of cisatracurium--effects on histamine release.

The purpose of this study is to evaluate the usefulness of Cisatracurium Besilat (CB), and the method of its administration during laparotomies on adult patients, to determine whether CB caused cutaneous, systemic or chemical evidence of histamine release. This study was conducted as a randomized, double-blind clinical trial on 38 patients (ASA I-II). After a standard anesthetic induction with fentanyl and propofol, patients received an i.

Pediatric obstructive sleep apnea syndrome and anesthetic management.

Sleep-related breathing disorders require special attention in children who spend a considerable time sleeping. Obstructive sleep apnea syndrome is characterized by episodes of upper airway obstruction during sleep. Symptoms include hyperactivity, enuresis, headache, failure to thrive, and increased respiratory effort and total sleep time.

[Tracheal rupture during esophagectomy].

Traumatic and iatrogenic injuries of the trachea are rare. The most common causes are motor vehicle, especially motorbike accidents. The incidence of tracheal rupture during esophagectomy is reported as 4-10 %.

[Pre-hospital airway management in trauma].

Knowledge of trauma is as old as mankind and survived a long way to reach new technologic developments. Being a multisystemic disease, trauma is an important social and financial problem especially in developing countries. Anesthesists possess important roles in the multisystemic management of trauma patients.

Effects of low and high intra-abdominal pressure on immune response in laparoscopic cholecystectomy.

Objective: Immunosuppression is directly related to the degree of trauma. The aim of this study is to compare the effects of low and high intra-abdominal pressure on immune response in moderate surgical trauma.

Methods: Twenty-two patients, scheduled for laparoscopic cholecystectomy, were randomly allocated to one of 2 groups according to intra-abdominal pressure: low and high intra-abdominal pressure.

[Anaesthesia in electroconvulsive therapy].

Electroconvulsive therapy (ECT) is a safe and efficient procedure performed for the treatment of drug resistant depression and other psychiatric disorders. Nowadays, its administration under general anaesthesia is a worldwide process. Anaesthetic management generally involves a short acting barbiturate such as thiopental in induction followed by a muscle relaxant.

Minimum effective dose of dexamethasone after tonsillectomy.

Background: The minimum effective dose of dexamethasone in conjunction with 50 microg x kg(-1) ondansetron was evaluated in the treatment for vomiting after elective tonsillectomy or adenotonsillectomy.

Methods: A total of 102 healthy children between 2 and 12 years of age participated in this prospective, randomized, double-blind study. A single intravenous (i.

Byler's disease and anesthetic consideration.

Byler's disease is an autosomal recessive condition characterized by intrahepatic cholestasis, progressive fibrotic changes and finally cirrhosis that leads to death during childhood. This is a report of a six-year-old girl with Byler's disease and retrobulbar hematoma as a result of trauma who underwent enucleation and implantation. This case report describes the anesthetic features of a patient with Byler's disease in which anesthetic agents with no or minimal hepatotoxic effect should be used to avoid deterioration of liver function.
