Abstract

Insights

Ondansetron effectively controls postoperative shivering, with 8 mg being the recommended dose, especially for patients experiencing nausea and vomiting. This study compared ondansetron to meperidine for treating shivering.

Area of Science:

  • Anesthesiology
  • Pharmacology

Background:

  • Postoperative shivering (POS) involves poorly understood neurotransmitter pathways.
  • 5-hydroxytryptamine 3 (5-HT3) receptor antagonists show promise in preventing POS.
  • Ondansetron, a 5-HT3 antagonist, is commonly used for postoperative nausea and vomiting.

Purpose of the Study:

  • To compare the efficacy of ondansetron and meperidine in treating shivering after general anesthesia.
  • To determine the optimal ondansetron dosage for managing postoperative shivering.

Main Methods:

  • A double-blinded randomized clinical trial involving 83 patients (18-60 years) experiencing shivering post-general anesthesia.
  • Patients were allocated to receive 4 mg ondansetron (n=27), 8 mg ondansetron (n=27), or 0.4 mg/kg meperidine (n=29) intravenously.
  • Surface temperatures, and the incidence and intensity of shivering were recorded.

Main Results:

  • Shivering control rates were 59% for 4 mg ondansetron, 81% for 8 mg ondansetron, and 86% for meperidine (P=0.01).
  • No significant differences in surface temperature were observed within groups.
  • Groups receiving ondansetron reported significantly lower incidence of nausea and vomiting compared to the meperidine group (P=0.01).

Conclusions:

  • Ondansetron and meperidine demonstrate comparable efficacy in managing postoperative shivering.
  • 8 mg of intravenous ondansetron is identified as the preferred dose for controlling shivering.
  • Ondansetron is particularly suitable for patients with postoperative shivering accompanied by nausea and vomiting.

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

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...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison

Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...

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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
