Abstract

Insights

Microvascular decompression surgery significantly increases the risk of postoperative nausea and vomiting (PONV) in neurosurgery patients. Identifying and managing risk factors is crucial for reducing PONV incidence after this procedure.

Area of Science:

  • Neurosurgery
  • Anesthesiology
  • Patient Safety

Background:

  • Postoperative nausea and vomiting (PONV) is a common complication following neurosurgery.
  • Limited data exists on the specific incidence and risk factors for PONV after microvascular decompression (MVD).

Purpose of the Study:

  • To investigate the incidence of PONV after microvascular decompression surgery.
  • To identify risk factors associated with PONV in patients undergoing craniotomy.
  • To determine if MVD is an independent risk factor for PONV.

Main Methods:

  • Retrospective review of 556 craniotomy cases over two years.
  • Identification of PONV within 24 hours postoperatively.
  • Multivariate logistic regression analysis to assess risk factors, including MVD.

Main Results:

  • Microvascular decompression was identified as an independent risk factor for PONV (OR 5.38).
  • Other significant risk factors included female gender, non-smoker status, intraoperative fentanyl, and cerebrovascular surgery.
  • 350 patients met the inclusion criteria from the initial 556 cases.

Conclusions:

  • Microvascular decompression surgery is a significant risk factor for PONV.
  • Prophylactic strategies should be considered to mitigate PONV risk in MVD patients.
  • Further research may explore targeted interventions for high-risk neurosurgical patients.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...
