Conversion of local anesthesia-guided deep brain stimulation of the subthalamic nucleus to general anesthesia.

Background: Deep brain stimulation of the subthalamic nucleus (STN) is a widely applied procedure in the treatment of patients with advanced Parkinson disease and is generally performed under local anesthesia. Here we report our experience with the conversion to general anesthesia in two patients with advanced Parkinson disease because of fear reactions intraoperatively.

Case Description: Patients received general anesthesia with propofol and were implanted with electrodes at the level of STN guided by multiple-microelectrode electrophysiological recordings after obtaining informed consent.

The optimal dose of remifentanil for acceptable intubating conditions during propofol induction without neuromuscular blockade.

Study Objective: To determine the optimal remifentanil dose required to provide acceptable intubating conditions following induction of anesthesia with propofol without using neuromuscular blockade.

Design: Dose-response study.

Setting: Operating room of a university hospital.

Hemodynamic responses and upper airway morbidity following tracheal intubation in patients with hypertension: conventional laryngoscopy versus an intubating laryngeal mask airway.

Objectives: We compared hemodynamic responses and upper airway morbidity following tracheal intubation via conventional laryngoscopy or intubating laryngeal mask airway in hypertensive patients.

Methods: Forty-two hypertensive patients received a conventional laryngoscopy or were intubated with a intubating laryngeal mask airway. Anesthesia was induced with propofol, fentanyl, and cis-atracurium.

Effect of intramuscular and intravenous lidocaine on propofol induction dose.

Objective: Our purpose was to study whether or not intravenous (IV) administration of lidocaine reduces propofol dose requirement as intramuscular (IM) lidocaine in a placebo-controlled manner.

Subjects And Methods: Seventy-five adult patients with American Society of Anesthesiologists physical status I and II, aged 20-60 years who were scheduled for surgery under general anaesthesia were included in the study. The patients were randomly allocated to 3 groups: IM: intramuscular administration; IV: intravenous administration and C: control.

Effects of different doses of remifentanil infusion on hemodynamics and recovery in children undergoing pediatric diagnostic cardiac catheterization.

Objective: The present study aimed to compare 2 different doses of remifentanil infusion on hemodynamics, recovery period, and complications in children undergoing diagnostic pediatric cardiac catheterization.

Design: A prospective study.

Setting: A university hospital.

Fatal fever of unknown origin in acute cervical spinal cord injury: five cases.

Background/objective: Patients with traumatic upper thoracic and cervical spinal cord injuries are at increased risk for the development of autonomic dysfunction, including thermodysregulation. Thermoregulation is identified as an autonomic function, although the exact mechanisms of thermodysregulation have not been completely recognized. Quad fever is a hyperthermic thermoregulatory disorder that occurs in people with acute cervical and upper thoracic spinal cord injuries.

Spinal-epidural anesthesia versus general anesthesia in the management of percutaneous nephrolithotripsy.

Objective: To compare the efficacy between combined spinal-epidural block and general anesthesia in patients undergoing percutaneous nephrolithotripsy (PNL).

Methods: A total of 180 patients undergoing PNL were randomly allocated to receive spinal-epidural anesthesia plus intravenous patient-controlled anesthesia with tramadol or general anesthesia (propofol induction, maintenance with sevoflurane) plus intravenous patient-controlled anesthesia with tramadol (G group). Hemodynamic changes, postanesthesia care unit (PACU) discharge times, times to home readiness, side effects, patient and endoscopist satisfaction, postoperative pain (scored from 0 to 10 on a visual analog scale), and analgesic medication were recorded.

Feasibility and safety of antegrade radial artery cannulation.

Background And Objective: The purpose of this study was to compare thrombosis rates in antegrade (catheter directed toward the hand) versus retrograde (catheter directed toward the elbow) cannulation of the radial artery. Our secondary objectives were to compare these two techniques in terms of success rate, differences in noninvasive versus invasive blood pressure measurement and complications.

Methods: After obtaining the approval of the local ethics committee and written informed consent, the patients were randomly allocated to the antegrade (group A, n=60) or retrograde (group R, n=60) groups.

Unilateral spinal anesthesia in two centenarian patients.

The use of unilateral spinal block with a specific hyperbaric mixture of bupivacaine and fentanyl in two centenarian women is presented. This technique was very effective in restricting sympathetic block, and it provided satisfactory analgesia and hemodynamic stability.

Ulnar artery versus radial artery approach for arterial cannulation: a prospective, comparative study.

Study Objective: To compare the ease of cannulation, success/failure rate, and complication rate between ulnar and radial arteries.

Design: Randomized, controlled study.

Setting: Operating room.

Remifentanil pretreatment reduces myoclonus after etomidate.

Study Objective: The aim of the study was to compare the effect of pretreatment with remifentanil 1 microg/kg and the effect of gender on the incidence of myoclonus after anesthesia induction with etomidate.

Design: This was a randomized, double-blind study.

Setting: The study was conducted at a university hospital.

[Comparison of effects of the administration of intraperitoneal local anesthetics for postoperative analgesia and prevention of shoulder pain].

Postoperative abdominal and shoulder pain are common complications after laparoscopy. The aim of this study is to compare the effects of intraperitoneal local anesthetics on postoperative abdominal and shoulder pain after laparoscopy. 55 women, physical status ASA I, who were undergoing diagnostic or minor gynecologic surgery, was enrolled to the study.

Comparison of ondansetron and meperidine for prevention of shivering in patients undergoing spinal anesthesia.

Background And Objectives: Perioperative hypothermia is a common problem in anesthesia practice. Regional anesthesia, like general anesthesia, influences the thermoregulatory process. The aim of our study was to compare the efficacy of ondansetron and meperidine in the prevention of shivering during and after spinal anesthesia.

[Seroprevalence of hepatitis B and C infections in surgical personnel and evaluation of predisposing factors].

The aim of this study was to investigate the seroprevalence of hepatitis B and C infections in the personnel of the operating room of Ondokuz Mayis University Hospital, to detect the carriers and actively infected individuals, to find out the health-workers' behaviours for the prevention from these infections, and to ascertain the risk factors of these diseases. HBsAg, anti-HBc, anti-HBs and anti-HCV antibodies were examined in the serum samples of 190 personnel, and their gender, education, working time (year), the daily working time in operating theatre (part/full time), the history of past hepatitis B infection, hepatitis B immunization, history of a past operation and blood transfusion, and the use of gloves during working (continuously-intermittent) were questioned. As a result, no carrier and/or actively infected personnel with hepatitis B and C were detected, while 36 (18.

Subdural hematoma as a late complication of spinal anesthesia.

Subdural hematoma is a rare complication of spinal anesthesia. This patient underwent bilateral inguinal herniorrhaphy under spinal anesthesia 40 days prior to admission. Two days after spinal anesthesia, the patient described a typical postdural puncture headache.
