Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Researchers will compare dexmedetomidine to fentanyl to see which drug provides better hemodynamic stability during spinal surgery.

Participants will :

* Receive either dexmedetomidine or fentanyl as part of their anesthesia during elective surgery
* Have their mean arterial pressure and heart rate measured at several time points during the procedure
* Be monitored throughout surgery to assess intraoperative hemodynamic responses and stability

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Spinal surgery is frequently associated with perioperative hemodynamic fluctuations and significant postoperative pain. Maintaining stable intraoperative blood pressure and heart rate is essential to minimize surgical bleeding, protect neural structures, and promote optimal recovery. Dexmedetomidine, a highly selective α₂-adrenergic receptor agonist, provides sedation, analgesia, and sympatholytic effects without causing respiratory depression and may contribute to improved cardiovascular stability during anesthesia. Fentanyl, a potent synthetic opioid, is widely utilized as an analgesic adjunct in general anesthesia but may offer less consistent hemodynamic control.

This study is a prospective, interventional, randomized, double-blind controlled trial conducted at Adam Malik General Hospital, Medan, Indonesia, following approval from the institutional ethics committee. A total of 50 adult patients scheduled for elective spinal surgery under general anesthesia were enrolled using consecutive sampling and randomly assigned to receive either dexmedetomidine or fentanyl as part of intraoperative management.

Eligible participants were aged 17-60 years and classified as American Society of Anesthesiologists (ASA) physical status I-III. Patients with known drug hypersensitivity, significant cardiac or vascular abnormalities, or contraindications to the study drugs were excluded.

Hemodynamic parameters, including mean arterial pressure (MAP) and heart rate, were recorded at baseline (T0) and at predetermined intraoperative time points (T1-T12). The primary outcome measure was intraoperative MAP, while secondary outcomes included heart rate and estimated blood loss. Statistical analyses were performed using independent t-tests or Wilcoxon rank-sum tests, with a significance threshold of p \< 0.05.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dexmedetomidine Group

Participants in this group received dexmedetomidine at a dose of 0.5 μg/kgBW/hour intravenously as part of anesthesia management for spinal surgery. The purpose is to evaluate the effect of dexmedetomidine on hemodynamic stability, including heart rate and mean arterial pressure, during and after induction of anesthesia.

Group Type EXPERIMENTAL

Dexmedetomidine

Intervention Type DRUG

Intravenous administration of dexmedetomidine at a dose of 0.5 μg/kgBW/hour during spinal surgery. Dexmedetomidine is a highly selective alpha-2 adrenergic agonist with sedative and analgesic properties. The aim is to evaluate its effect on maintaining hemodynamic stability, including mean arterial pressure (MAP) and heart rate, during and after anesthesia induction.

Fentanyl Group

Participants in this group received fentanyl at a dose of 1.5 μg/kgBW/hour intravenously as part of anesthesia management for spinal surgery. This arm serves as the comparison group to evaluate differences in hemodynamic parameters such as heart rate and mean arterial pressure compared to dexmedetomidine.

Group Type EXPERIMENTAL

fentanyl

Intervention Type DRUG

Intravenous administration of fentanyl at a dose of 1.5 μg/kgBW/hour during spinal surgery. Fentanyl is a potent synthetic opioid analgesic used to manage pain and modulate hemodynamic responses during surgery. This group serves as the comparator to evaluate differences in hemodynamic parameters, particularly MAP and heart rate, compared to dexmedetomidine.
