概括

麻醉诱导期间的口罩通风可能会导致胃灌气并增加腹内压力 (IAP). 这项研究在手动,压力控制和体积控制的通风模式之间没有发现IAP的显著差异,但PCV提供了更好的呼吸稳定性.

科学领域:

麻醉学麻醉学
关键护理医学关键护理医学
外科手术的安全性

背景情况:

在麻醉诱导过程中,不适当的口罩通风会导致胃张张和腹内压力升高 (IAP).
这增加了反流和肺吸气的风险.
了解不同通风模式对IAP的影响对于患者安全至关重要.

研究的目的:

为了比较手动通风 (MV),压力控制通风 (PCV) 和体积控制通风 (VCV) 在麻醉诱导期间对IAP的影响.
为了观察输管管术后IAP的动态变化和自发呼吸的恢复.
评估术后恶心和吐 (PONV) 的发生率.

主要方法:

一个单盲随机对照试验,涉及152名接受腹腔镜手术的患者.
参与者被随机分配到三个通风组 (MV,PCV,VCV),控制气道压力和潮体积.
内压力被用来间接测量IAP.

主要成果:

在所有组中,IAP下降,没有显著的跨组差异.
在VCV组中,胃 insufflation与更高的IAP和高峰气道压力有关.
PCV组显示出更大的潮体积传递和更低的PaCO2,在组间的PONV发病率上没有显著差异.

结论:

虽然所有三种通风模式都相对减少了IAP,但胃灌气影响了VCV组中的IAP.
由于持续的潮体积和较低的PaCO2,PCV可能在呼吸系统稳定性方面具有优势.
需要对更大的样本进行进一步的研究,以确认PCV的益处.

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

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

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 Antagonists

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...

Blind Procedures

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

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

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...

Pathophysiology of Vomiting

Pathophysiology of Vomiting

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...
