Summary
A simplified algorithm for postoperative nausea and vomiting (PONV) prophylaxis significantly reduced PONV incidence. This improved adherence to guidelines, demonstrating the effectiveness of a streamlined approach in clinical practice.
Area of Science:
- Anesthesiology
- Clinical Pharmacy
- Patient Safety
Background:
- Poor adherence to existing guidelines for preventing postoperative nausea and vomiting (PONV) is a recognized challenge.
- This study addresses the gap by evaluating a simplified PONV prophylaxis algorithm.
Purpose of the Study:
- To assess the impact of a simplified PONV prophylaxis algorithm on PONV incidence.
- To evaluate the effect of algorithm simplification on adherence to PONV prevention guidelines.
Main Methods:
- A before-and-after study design was employed, involving two audits of patient records.
- Adherence to PONV prophylaxis guidelines and PONV incidence were assessed in adult patients undergoing elective non-cardiac surgery.
- A simplified algorithm was implemented, differentiating prophylaxis based on patient sex.
Main Results:
- The simplified algorithm led to a significant reduction in overall 24-hour PONV incidence (33% to 22%, P=0.02).
- Adherence to PONV prophylaxis guidelines significantly improved post-simplification (18% to 46%, P=0.0001).
- PONV incidence within 1 hour remained comparable between the two study periods.
Conclusions:
- Simplifying the PONV prophylaxis algorithm significantly decreases PONV incidence.
- The simplified algorithm enhances compliance with established PONV prevention protocols.

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
802
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.

01:27Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
715
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,...

01:29Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
932
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.

652
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...

01:22Pathophysiology of Vomiting
3.2K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
