Summary
A new Nausea and Vomiting Thermometer Scale (NVTS) was developed for pediatric cancer patients. The scale demonstrated strong reliability and validity, offering a valuable tool for assessing nausea and vomiting in this population.
Area of Science:
- Pediatric Oncology
- Nursing Research
- Measurement Tools
Background:
- Nausea and vomiting are significant side effects in children undergoing cancer treatment.
- Accurate assessment tools are crucial for managing these symptoms effectively.
Purpose of the Study:
- To develop and validate the Nausea and Vomiting Thermometer Scale (NVTS) for pediatric cancer patients.
- To establish a reliable and valid instrument for quantifying nausea and vomiting severity.
Main Methods:
- A methodological study involving 250 children with cancer in Turkey.
- Statistical analyses included t-test, ROC analysis, regression, ICC, and Bland-Altman analysis.
- Scale-level content validity index (CV I) was calculated.
Main Results:
- The NVTS achieved a scale-level CVI of .94, indicating coherence.
- ROC analysis determined a cut-off point of three for the scale.
- The NVTS demonstrated excellent reliability with an ICC of .99.
- Linear regression explained 44.9% of nausea and vomiting status based on chemotherapy, type, and vomiting frequency.
- Bland-Altman analysis confirmed insignificant correlation between differences and means.
Conclusions:
- The Nausea and Vomiting Thermometer Scale (NVTS) is a reliable and valid instrument for assessing nausea and vomiting in children with cancer.
- The NVTS provides a quantifiable measure to aid in symptom management and treatment evaluation.
- Further research can explore the NVTS's utility in diverse pediatric oncology settings.

01:29Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
543
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.

01:27Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
390
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,...

01:28Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
296
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...

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
419
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.

01:22Pathophysiology of Vomiting
1.5K
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...

01:27Assessing Body Temperature - Rectal
7.5K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...
