Abstract:

Objective

To investigate the effects of different doses of oxycodone combined with dexmedetomidine on blood oxygen saturation and emergence agitation in patients undergoing laparoscopic cholecystectomy (LC).

Methods

A total of 270 elective LC patients treated at Ankang Central Hospital from June 2021 to December 2024 were enrolled (117 males, 153 females; aged 36-55 years, mean 46.8±9.9 years). Using a computer-generated random number table, patients were assigned to group A (oxycodone 0.05 mg/kg), group B (0.15 mg/kg), or group C (0.25 mg/kg) during anesthesia induction; all groups received dexmedetomidine 0.5 µg/kg, 90 cases in each group. Saturation of peripheral oxygen (SpO2), sedation agitation scale(SAS), heart rate (HR), mean arterial pressure (MAP), postoperative visual analogue scale (VAS), and adverse events were compared among the three groups at pre-induction, extubation, and 30 min post-operatively.

Results

No baseline differences (age, gender, BMI, ASA, operation/anesthesia time, comorbidities, smoking) across groups (P>0.05). Group C showed lower 1/6/12 h VAS vs A/B (P<0.001), but reduced SpO2 at extubation and 30 min post-op (P<0.05). Intraoperative and extubation HR/MAP were minimal in Group C (P<0.001). Its 51.1% adverse event rate exceeded low-dose groups’ 17.8% (P<0.001). Agitation rates rose by dose (11.1%, 16.7%, 24.4%), no statistical difference (P>0.05).

Conclusion

Oxycodone combined with dexmedetomidine improves post-operative analgesia after laparoscopic cholecystectomy; however, higher doses may increase the risks of respiratory depression, hemodynamic fluctuation, and emergence agitation.
