Effect of Nalbuphine on Hemodynamic Response During Laryngoscopy and Intubation

Summary

Laryngoscopy and placement of a breathing tube during general anesthesia can cause temporary increases in blood pressure and heart rate. These changes may be harmful in some patients. Nalbuphine is an opioid pain medicine that may reduce these cardiovascular responses.

This study evaluated whether intravenous nalbuphine, given before anesthesia induction, reduces changes in mean arterial blood pressure during laryngoscopy and orotracheal intubation compared with placebo (normal saline).

Adult patients undergoing elective surgery under general anesthesia were randomly assigned to receive either nalbuphine or placebo before anesthesia. Blood pressure was measured before drug administration, during intubation, and for several minutes afterward. The results of this study may help guide safe medication use to maintain blood pressure stability during airway management.

Conditions

  • Hemodynamic Response to Laryngoscopy and Orotracheal Intubation

Interventions

DRUG

Normal saline IV

Intravenous administration of normal saline in a volume equivalent to the nalbuphine dose, 5 minutes prior to induction of general anesthesia for elective surgery. This serves as a placebo control to compare the effect of nalbuphine on attenuation of the hemodynamic response (mean arterial pressure and heart rate) during laryngoscopy and orotracheal intubation. Standard monitoring is applied during the procedure. Any adverse events are recorded similarly to the experimental group.

DRUG

Nalbuphine 0.2 mg/kg

Intravenous nalbuphine at a dose of 0.2 mg/kg administered 5 minutes prior to induction of general anesthesia for elective surgery. The purpose of administration is to attenuate the hemodynamic response, specifically mean arterial pressure and heart rate changes, associated with laryngoscopy and orotracheal intubation. Standard monitoring is applied during the procedure, including continuous ECG, non-invasive blood pressure, pulse oximetry, and capnography. Any adverse events such as mild bradycardia or nausea are recorded.
