Chronic Cannabis Intoxication and Propofol-Induced Salivation: Causes and Considerations

Summary
Cannabis use may increase saliva production during propofol anesthesia, a condition termed cannabis-induced hypersalivation after propofol (CHAP). This can pose suffocation risks during procedures, requiring careful management.
Area of Science:
- Anesthesiology
- Pharmacology
- Cannabis Research
Background:
- Increasing cannabis legalization leads to more patients with recent exposure to recreational or medical cannabis.
- Limited data exists on interactions between cannabis use and propofol anesthesia, particularly for procedures like those in the oropharynx.
Purpose of the Study:
- To describe three cases of 'cannabis-induced hypersalivation after propofol' (CHAP).
- To present institutional experience with this unique pharmacological interaction.
- To evaluate potential pharmacological mechanisms and management strategies for CHAP.
Main Methods:
- Case series reporting on three patients experiencing hypersalivation post-propofol anesthesia with recent cannabis use.
- Review of potential pharmacological interactions between cannabis compounds and propofol.
- Discussion of clinical implications and management options for procedure-related hypersalivation.
Main Results:
- Three cases of significant hypersalivation were observed in patients who had recently used cannabis prior to propofol anesthesia.
- This hypersalivation, termed CHAP, complicated oropharyngeal procedures.
- Potential pharmacological interactions contributing to increased salivation were evaluated.
Conclusions:
- Cannabis use may be associated with increased intraoperative hypersalivation when combined with propofol anesthesia (CHAP).
- CHAP presents a potential procedural risk, including suffocation, necessitating awareness and management strategies.
- Further research into the pharmacodynamics of cannabis-propofol interactions is warranted.

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
365
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.

01:24Parenteral Anesthetics: Overview
192
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

01:27CNS Depressants: Alcohol and Nicotine
353
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
323
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

01:20Inhalational Anesthetics: Overview
490
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

01:14Prevention of Further Absorption of Poison
919
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
