Randomized Controlled Trial Clinical Trial[Nausea and vomiting after gynecologic laparoscopies].
To investigate the occurrence of postoperative nausea and vomiting (PONV) in relation to the menstrual cycle in patients anaesthetised with isoflurane and propofol. ⋯ The incidence of PONV is significantly higher when patients undergo laparoscopy during the first 8 days of the menstrual cycle. When compared to isoflurane, propofol results in a significantly lower incidence of PONV and postoperative shivering and a lower occurrence of postoperative pain.

Randomized Controlled Trial Comparative Study Clinical Trial[Randomized use of an active compression-decompression technique within the scope of preclinical resuscitation].
Despite its worldwide propagation, external chest compression is of limited efficacy. Recently a new method of cardiac resuscitation, active compression-decompression (ACD), was presented. In animals and a small series of patients resuscitated within the hospital ACD proved to augment blood flow during cardiac resuscitation as a result of greater intrathoracic pressure gradients. ⋯ Methods to verify the efficacy of ACD in dummy training should be developed. Paramedics performing ACD should relieve each other every 5 minutes. In patients resuscitated by ACD self-adhesive defibrillation paddles instead of electrode gel should be used. Modifications in the design of the CardioPump are desirable to enhance the efficacy of ACD. With regard to future multicentre trials all paramedics should be skilled in the new technique to reach more patients in a shorter period of time.

Randomized Controlled Trial Clinical Trial[Comparison of 5% human albumin and 6% 200/0.5 HES as exclusive colloid components in large surgical interventions].
It was the purpose of the following study to compare effects of 6% hydroxyethyl starch 200/0.5 (HES) and albumin 5% (HA5) on haemostasis, haemodynamics, oncotic function and plasmatic homoeostasis. ⋯ Regarding total blood output/intake, haemodynamic functions, haematological parameters, coagulation, oncotic function, and plasmatic homoeostasis, HES is a safe colloid if contra-indications are taken into account, capable of replacing albumin 5% entirely as a colloid component of treatment of even large blood losses intraoperatively above the recommended dose of 20 ml/kg BW/d.

Randomized Controlled Trial Clinical Trial[Abdominal complications following heart surgery].
Intra-abdominal complications occurring after cardiopulmonary bypass operations are rare but often fatal. There are only speculative approaches concerning the pathogenesis and the risk factors of these complications. The aim of our study was therefore to determine the causative factors and to evaluate the diagnostic and therapeutic measures, because early diagnosis and immediate treatment is essential for the outcome of the patients. ⋯ In reviewing both our results and data cited in earlier studies, intra-abdominal complications can generally be attributed to the following: Intraoperative surgical complications with the consequence of prolonged aortic cross clamping and total bypass times can cause low cardiac output and mesenteric hypoperfusion. Predominantly as a result of the low cardiac output, the use of vasopressors increases splanchnic ischaemia, in particular in patients with pre-existing occlusive vascular disease of the mesenteric arteries. Mucosal ischaemia might be aggravated by a concurrent pseudo-obstruction. On the other hand, intraoperative complications and low cardiac output can cause further complications and finally multiple organ failure. Multiple organ failure and ischaemia of the gut can initiate the vicious circle which is responsible for the high mortality from these complications. Early detection by careful physical examination and the combination of the diagnostic procedures and prompt treatment should lead to a reduction of mortality.

Randomized Controlled Trial Clinical Trial[Pharmacodynamic effects of the phosphodiesterase inhibitor enoximone during exposure to the volatile anesthetics halothane and isoflurane in coronary surgery patients].
We investigated the pharmacodynamic effects of the phosphodiesterae inhibitor enoximone in the presence of halothane and isoflurane in 20 patients, ASA class III, aged 45-75 years, undergoing coronary artery bypass grafting. The study was approved by the local Medical Ethics Committee and patients' informed written consent was obtained. ⋯ Our results suggest that in the presence of halothane or isoflurane the phosphodiesterase inhibitor enoximone produces a comparable increase in cardiac output and decrease in systemic vascular resistance in patients with coronary artery disease.
