Acute intravenous premedication with nalbuphine

Area of Science:

• Anesthesiology
• Pharmacology
• Surgical Care

Background:

• Premedication is crucial for managing patient comfort and physiological stability during surgery.
• Opioid analgesics are commonly used for pain management and sedation.
• Evaluating the comparative effects of different analgesics is essential for optimizing perioperative care.

Purpose of the Study:

• To compare the effects of intravenous nalbuphine, morphine, and placebo as premedication in adult surgical patients.
• To assess the impact on minute ventilation, immediate side effects, postoperative pain, and postoperative nausea and vomiting.

Main Methods:

• A randomized, double-blind study involving 75 adult surgical patients.
• Intravenous administration of nalbuphine (0.1 mg/kg), morphine (0.1 mg/kg), or placebo 12-16 minutes before anesthesia induction.
• Comparison of outcomes across the three treatment groups.

Main Results:

• Both nalbuphine and morphine significantly reduced minute ventilation and increased immediate side effects compared to placebo.
• Morphine effectively managed early postoperative pain, eliminating the need for additional medication.
• Nalbuphine was associated with a lower incidence of postoperative nausea and/or vomiting than both morphine and placebo.

Conclusions:

• Nalbuphine and morphine demonstrate significant physiological effects and side effect profiles when used as premedication.
• Morphine provides superior early postoperative analgesia.
• Nalbuphine may be a favorable option for reducing postoperative nausea and vomiting in surgical settings.
