Study summary

This study aims to compare the quality of perioperative antiemesis of palonosetron and ondansetron in patients undergoing cesarean section

Read the detailed description

Perioperative nausea and vomiting (PONV) related to spinal block anesthesia are common events and unpleasant for pregnant women. Its incidence can reach 80% in high-risk patients, and remains high despite the emergence of new antiemetic drugs.

Episodes untreated can result in prolonged stay in post-anesthetic care unit (PACU) and rehospitalization which can result in significant increase in overall costs of health care.

The purpose of the prophylaxis of PONV is therefore decrease its incidence, the stress of the patient, improve the quality and safety of surgical procedure and reduce hospital costs.

Antagonists of the 5-hydroxytryptamine 3 subtype receptor have been widely used and effective against PONV due to its efficacy and a favorable side-effect profile. Palonosetron is a new and potent drug generation5 second-HT antagonist with improved profile that acts longer. Recent studies where it was compared to ondansetron and palonosetron in high-risk patients in head and neck surgery and laparoscopic surgery is disclosed palonosetron far superior to ondansetron especially 2-24 hours after surgery. But there are no studies on caesareans comparing the two drugs.

This prospective, randomized, double-blind, placebo controlled, was designed to evaluate the efficacy of palonosetron compared with ondansetron and placebo for the prevention of nausea and vomiting in patients undergoing cesarean delivery under spinal anesthesia.

What researchers measure

Primary outcomes

  1. Number of participants with nausea and vomiting

    Time frame: Within the first 48 hours after surgery

Secondary outcomes

  1. Nausea Scores on the Number Rating Scale

    Quantify nausea by Number Rating Scale (NRS, ranging from 0 to 10 cm, zero being found when the patient is no nausea and ten, with maximum or un bearable nausea

    Time frame: Within the first 48 hours after surgery

  2. Nausea Scores on the Verbal Rating Scale

    Verbal Rating Scale (VRS), consisting of a list of phrases (no nausea, mild nausea, moderate nausea, intense nausea, maximum nausea)

    Time frame: Within the first 48 hours after surgery

  3. Apgar Newborn

    The resulting Apgar score ranges from zero to 10, measured at first and fifth minute

    Time frame: delivery

  4. Likert Scale

    Overall satisfaction with the nausea - vomiting experience in a Likert scale of four points (dissatisfied, neutral, satisfied and very satisfied)

    Time frame: 48 hours after surgery

  5. Number of participants with adverse events as a measure of safety and tolerability

    Intraoperative hemodynamic stability analysis through the incidence of tachycardia, hypertension, bradycardia, hypotension and consumed vasopressors

    Time frame: delivery

  6. Number of participants with adverse events as a measure of safety and tolerability

    Incidence of adverse effects such as nausea, vomiting, pruritus, urinary retention, drowsiness and consumed rescue antiemetics

    Time frame: Within the first 48 hours after surgery
