the effect of cold vapor on nausea and vomiting in the early postoperative period after laparoscopic cholecystectomy

Conditions: Laparoscopic Cholecystectomy; Postoperative Nausea; Postoperative Vomiting

Summary: postoperative nausea and vomiting (ponv) was defined by the american society of perianesthesia nurses (aspan) as nausea and/or vomiting in the first 24 hours after surgery and is among the most common complications after pain in patients undergoing surgery. ponv is divided into three as early, late, and delayed. nausea-vomiting developing within 2-6 hours after surgery is classified as early, nausea-vomiting developing within 6-24 hours after surgery is classified as delayed, and nausea and/or vomiting developing within the first 24 hours after surgery are classified as delayed ponv. ponv increases the length of stay in the recovery room, delays starting oral intake, causes fluid and electrolyte imbalance, and causes pain, dehydration, delayed wound healing, decreased patient comfort, prolonged hospitalization, and increased cost. therefore, the prevention and management of nausea and vomiting in the perioperative period in surgical patients are very important.

postoperative nausea and vomiting (ponv) was defined by the american society of perianesthesia nurses (aspan) as nausea and/or vomiting in the first 24 hours after surgery and is among the most common complications after pain in patients undergoing surgery. ponv increases the length of stay in the recovery room, delays starting oral intake, causes fluid and electrolyte imbalance, and causes pain, dehydration, delayed wound healing, decreased patient comfort, prolonged hospitalization, and increased cost. therefore, the prevention and management of nausea and vomiting in the perioperative period in surgical patients are very important. in a meta-analysis study that included data from eleven countries, the prevalence of ponv was 27.7%, the prevalence of postoperative nausea was 31.4% and the prevalence of post-operative vomiting was 16.8%. in a study conducted in turkey, it was reported that 45.9% of surgical patients had nausea and 23.6% had vomiting in the postoperative period. in another study conducted in the postoperative recovery unit, it was reported that 29% of the patients experienced nausea and vomiting. the risk of ponv may vary depending on the patient, anesthesia, and surgical intervention. patient-related risk factors include female gender, young age (under 50 years of age), obesity, history of motion sickness; anesthesia-related risk factors include the type of anesthesia, duration of administration, use of volatile anesthetics, opioids, and nitrous oxide; among the risk factors for previous surgical interventions are laparoscopic, bariatric, gynecological and cholecystectomy surgeries. pharmacological treatment, non-pharmacological treatment methods, or both are used in the management of ponv in patients undergoing surgical intervention. today, a multimodal approach is recommended in the management of ponv in early recovery protocols in surgical patients. antiemetic drugs used among pharmacological methods can cause side effects such as headache, constipation, drowsiness, tremor, irregular heartbeat, and wound infection. therefore, non-pharmacological treatment methods have an important place in care practices. in the literature, there are many studies on the successful application of non-pharmacological treatment methods such as massage, progressive relaxation exercises, hypnosis, acupuncture, yoga, acupressure, transcutaneous electrical nerve stimulation, music therapy, herbal treatments, and aromatherapy in the prevention of ponv. the cold application creates vasoconstriction in the vessels in the area where it is applied, decreases the metabolic rate, and reduces edema. the cold application reduces muscle temperature by reducing the tension sensitivity of muscle spindles with the reflex effect of heat receptors or inactivating trigger points in the muscles and helps to reduce muscle spasm. thus, it reduces skin sensitivity by lowering the temperature of nerve fibers and receptors. cold application is especially beneficial in post-traumatic pain, swelling, and muscle spasm. temperature can affect the release of odorous volatile substances in drugs. the cold application also has clinically important potential effects on nausea caused by unpleasant tastes by reducing the olfactory component of negative aromas. cold can be applied in different ways. one of them is administration by inhalation. in the literature, there are studies on the positive effects of cold vapor application on sore throat, cough, swallowing, and hoarseness. in a study, it was determined that postoperative nausea and vomiting were less in patients who received oral care with the cold application after laparoscopic myomectomy compared to the control group. there is no study in the literature examining the effect of cold vapor application on ponv.
