Filter by:The purpose of this randomized clinical trial is to evaluate the interaction of intravenous fluid therapy during otorhinolaryngological surgery, on postoperative vomiting. The hypothesis is that perioperative supplemental intravenous fluid administration reduces the incidence of postoperative vomiting.
Postoperative pain, nausea and vomiting (PONV) are the most common complications after anesthesia and surgery. Women undergoing mastectomy with axillary dissection are at a particularly high risk for the development of PONV and an incidence of 60-80% in patients receiving no antiemetic has been reported. Emetic episodes predispose to aspiration of gastric contents, wound dehiscence, psychological distress, and delayed recovery and discharge times. These justify the use of prophylactic antiemetics in women scheduled for mastectomy. Most of the currently used antiemetics, including antihistamines, butyrophenones and dopamine receptor antagonists have been reported to cause occasional undesirable adverse effects, such as excessive sedation, hypotension, dry mouth, dysphoria, hallucinations and extrapyramidal signs. Antiserotonins (e.g., ondansetron) are available for the prevention and treatment of PONV in patients undergoing various types of surgery [4]. However, the use of prophylactic antiemetic therapy with antiserotonins has been criticized for being too expensive. Dexamethasone was first reported to be an effective antiemetic regimen in patients receiving cancer chemotherapy. The purpose of this study was to evaluate the efficacy of dexamethasone treatment for reducing pain and PONV as well as analgesic and antiemetic requirements in women undergoing general anesthesia for mastectomy with axillary lymph node dissection.
Postoperative nausea and vomiting (PONV) remain a significant challenge in the investigators practice. However, pharmaceutical prophylaxis can imply unpleasant adverse effects. It would therefore be appropriate to consider the use of non-pharmacological methods in preventing PONV. Acupuncture and acupressure are reported to be effective preventive treatment for PONV, and the adverse effects are minimal. Consequently, the investigators will investigate if acupuncture and acupressure can be implemented as a supplementary to the ordinary treatment in children undergoing surgery for tonsillectomy and/or adenoidectomy. The study will also focus on the feasibility for acupuncture and acupressure in the operation theatre. The study and inclusion/exclusion decisions are conducted after the "intention-to-treat" principle. 126 patients are included, divided into two groups: 1. Treatment Group - standard treatment and acupuncture performed after induction of anaesthesia, acupressure administered before awakening 2. Control Group - standard treatment The primarily endpoints in this study are nausea, retching and vomiting. The effect of acupuncture/acupressure will be studied with regard to any association with possible factors of predisposition to PONV, as well as with other factors registered during the study. Adverse effects from the acupuncture site and wristband will be registered.
The purpose of this study is ad 1) to measure the depth of hypnosis as assessed by BIS and cAAI during an average general anesthesia with xenon or sevoflurane and to establish a reliable monitoring system for measuring and documenting the actual depth of hypnosis for the volatile anesthetics investigated. Ad 2) the question is to be answered whether 4 mg dexamethasone i.v. is an effective prophylactic treatment against postoperative nausea and vomiting in case of xenon or sevoflurane anesthesia. Ad 3) it serves to gain evidence about the (non-)effectiveness and kinetics of ondansetron as antiemetic remedy after xenon or sevoflurane anesthesia.
