Association between intraoperative hypotension and postoperative nausea and vomiting: a retrospective analysis of 247 thyroidectomy cases

Comparison of incidents of nausea and vomiting between general anesthesia With Endotracheal tube and spinal anesthesia in cesarean sections

“…The incidence of nausea during the first 6 hours after surgery (P=0.17) and throughout the next 6 to 24 hours (P=0. 24) was not statistically different between the two groups (33). furthermore In a randomized controlled trial conducted in Iran, the average nausea score at 30 minutes, 60 minutes, 90 minutes, 120 minutes, 2 hours, 4 hours, and 6 hours following surgery in elective cesarean section under spinal anaesthetic was significantly lower than the placebo.…”

“…The correlation among type of antiemetic and need for second or more dosages of drug shown that metoclopramide achieved a significant value of (14.5%) in parturient who underwent spinal anesthesia (table 6) in line study In terms of the need for rescue antiemetic medication in the recovery room, there was a statistically significant difference between the ondansetron and metoclopramide groups (P=0.024): 6 (20%) of the origin 30 participants in the metoclopramide group required an additional dose of medication, whereas the ondansetron group did not record any such need. (33) Other studies found that 20 mg of metoclopramide was ineffective, presumably due to the small sample sizes (40, 129, and 51 patients per group) (34) (35) .In the end no single antiemetic medication has proven to be an all-encompassing treatment for postoperative nausea and vomiting. The addition of 25 mg or 50 mg metoclopramide to the standard intervention of 8 mg dexamethasone was found to be efficacious, safe, and inexpensive.…”

The Correlation of Intraoperative Blood Pressure with Post Operative Nausea and Vomiting Incidence

“…In accordance with Nakatani et al ( 2021) study described that hypotension is one of the factors that trigger PONV regardless of anesthesia, the mechanism that causes PONV by hypotension is not clear, but the reduction of blood flow to the brain stem and its influence on the chemoreceptor trigger zone (CTZ) can cause dizziness and disturbances in the vestibular system, leading to nausea or vomiting. Although the mechanism of nausea and vomiting has not been fully elucidated, PONV is thought to be induced by stimulation of the vomiting center from the vestibular organs (Nakatani et al, 2021).…”

“…Post Operative Nausea and Vomiting (PONV) is a complication of general anesthesia that often co-occurs with pain. PONV causes discomfort to the patient, which can be an obstacle to early recovery (Nakatani et al, 2021). PONV was defined as postoperative nausea and vomiting that occurred within 24 hours of surgery.…”

“…Hypotension is a well-known factor that triggers nausea and vomiting regardless of anaesthesia. The exact mechanism that causes PONV by hypotension is unclear, but reduced blood flow to the brainstem and effects on the CTZ can cause dizziness and disturbances in the vestibular system, leading to nausea or vomiting (Nakatani et al, 2021).…”
