AIM The aim of this study was to investigate the effect of 15 ml bupivacaine 0.25%, given via an epidural catheter, on the tissue-PO2 of the colon wall in humans. METHODS Nine patients were studied during elective colorectal surgery. The tissue-PO2 was measured by polarography, using a multiwire surface probe. RESULTS There was no significant change in(More)
BACKGROUND AND OBJECTIVE Factors which lead to prolonged stay in the day-care unit and unplanned admission after day-case surgery are poorly understood. METHODS Data sets of 3152 day-case patients were collected with a computerized online record keeping system (NarkoData). Predictors of prolonged postoperative stay including unanticipated admission were(More)
BACKGROUND The aim of this investigation was to compare routine balanced anaesthesia with different inhalation agents to intravenous anaesthesia (IVA) using an Anaesthesia-Information-Management-System (AIMS) with regard to time of recovery from anaesthesia, the time of discharge from the postanaesthesia care unit (PACU) and postoperative nausea as well as(More)
UNLABELLED Inhaled nitric oxide (NO) at 20 or 40 ppm does not improve arterial oxygenation during one-lung ventilation (OLV). The authors hypothesized that NO at smaller concentrations might improve oxygenation. Twelve piglets weighing 26 to 32 kg were studied. When PaO(2) had reached a plateau during OLV, NO at doses of 4, 8, 16, and 32 ppm were randomly(More)
Somatosensory evoked responses after median nerve stimulation were recorded in 21 patients during hypothermic cardiopulmonary bypass. During hypothermia a significant linear correlation (P less than 0.001) was found between evoked potential latency and temperature. Correlation was best for tympanic membrane temperature during cooling and for perfusate(More)
OBJECTIVE To study the influence of low-dose dopexamine on splanchnic oxygenation during major abdominal surgery. DESIGN Prospective, randomized, placebo-controlled study. SETTING University hospital. PATIENTS Eighteen adult patients undergoing elective major abdominal surgery. INTERVENTIONS The patients received either dopexamine at 1 microg/kg/min(More)
BACKGROUND In a pilot study, the haemodynamic and gas exchange effects of acute hypercapoia during one-lung ventilation in thoracotomy patients were investigated. The effects of normocapnic one-lung ventilation (OLV-N) on haemodynamics and pulmonary gas exchange were compared with those of hypercapnic one-lung ventilation (OLV-H) in 14 patients undergoing(More)
OBJECTIVE The aim of this retrospective study was to assess the suitability of routine data gathered with a computerized anesthesia record keeping system in investigating predictors for intraoperative hypoxemia (SpO2 < 90%) during one-lung ventilation (OLV) in pulmonary surgery. METHODS Over a four-year period data of 705 patients undergoing thoracic(More)
The usefulness of body plethysmography in the assessment of thoracotomy candidates is not well documented. Reported thresholds for operability are generally expressed in absolute values, which do not take into account a patient's size, age or gender. Spirometric and plethysmographic data of 103 patients undergoing thoracotomy were examined for their ability(More)
