Filter by:Many factors during laparascopic surgery leads to PONV (postoperative nausea and vomiting), such as C02 insufflations causing peritoneal stretch and irritation and type of anaesthesia given during surgery. The two anesthetic techniques used in bariatric surgery are gas anesthesia (Remifentanil TCI and Desfluran) and Total Intra Venous Anesthesia (TIVA) with propofol. There are studies which have shown a reduction in postoperative nausea and vomiting following TIVA, and there are publications showing no statistically significant difference. The aim of this study was to investigate the best anaesthetic approach for obese subjects, evaluating awakening time, postoperative nausea and pain. Our hypothesis was based on the fact that Propofol is a lipid-soluble anesthetic and therefore might have a prolonged effect in obese patients, leading to a longer awakening time along with postoperative nausea and vomiting. This hypothesis is also described earlier by obese patients have more depots (bulk fat) and also more fat surface making anaesthetics storage more easier, and also that the anesthetic will return into the circulation when the administration is stopped [18].
Approximately 20% women who undergo cesarean delivery would suffer from severe post-operative pain, which may further increase their risks from developing postpartum depression. Predictive factors such as pre-operative pain, age and anxiety could significantly contribute to post-operative nausea and vomiting (PONV) and pain in general surgery, however little information is available with regards to cesarean delivery. The investigators would investigate the risk factors of causing post-operative emesis after cesarean delivery, and to reaffirm that there is a positive correlation between pain on local anesthetic injection, presence of mechanical temporal summation (MTS) and post-Cesarean pain scores.
Local intra-articular injection of anesthetics (LIA) is increasingly used during knee arthroscopy for pain relief. The LIA can only be performed at the end of surgery as the knee joint is continuously flushed during the arthroscopy. As a consequence, an optimal analgesic effect is only obtained one hour after surgery and opiates are typically used as pain relief in the immediate postoperative period. Since these opiates have a number of side effects such as nausea, vomiting and drowsiness, other analgetic methods are desirable. Intravenous administration of lidocaine, a safe, inexpensive analgesic, is already used in major (abdominal) surgeries and might also be a promising method for pain relief in the first hour after knee arthroscopy, in anticipation of the onset of the analgesic effect of the LIA. The aim of this study is to verify if systemic administration of lidocaine has a beneficial effect on the pain immediately after knee arthroscopy. In addition, the effect of systemic lidocaine administration on postoperative nausea, vomiting and general patient comfort will be evaluated.
Aromatherapy has been proven to be effective for treating patients with postoperative nausea and vomiting (PONV) after surgery, but few studies analyze its effect on preventing PONV. Most studies use aromatherapy once patients become nauseous, but this study will address a gap in the literature with relation to the effect of aromatherapy in the prevention of PONV.
