정맥 내 자가 조절 진통을 받는 환자의 술 후 초기 통증 조절을 위한 진통제의 비교 = Comparison of three parenteral injection methods for early postoperative pain control in patients with intravenous patient-controlled analgesia (IV PCA)

다국어 초록 (Multilingual Abstract)

Background: This study was performed to compare postoperative
pain and sedation among meperidine 50 mg PRN intramuscular
injection, meperidine 50 mg routine intramuscular injection and
fentanyl 50μg routine intravenous injection at the end of surgery
for early postoperative pain control in patients with intravenous
patient-controlled analgesia (IV PCA).
Methods: In group P (n = 35), meperidine 50 mg was injected
intramuscularly on request of patients. In group M (n = 35) and
F (n = 35), meperidine 50 mg was injected intramuscularly or
fentanyl 50μg was injected intravenously at the end of surgery,
respectively. Pain score was measured with verbal rating scale
(VRS; 0−10) at 30 min, 1 hr, and 6 hr, and sedation score was
evaluated with Observer’s assessment of alertness/sedation scale
(OAA/S) at 30 min, and 1 hr after extubation. Additional fentanyl
50 μg was injected intravenously if patient requested pain control
in group P and if VRS was higher than 5 point at 30 min after
extubation or patients requested pain relief in group M and group
F.
Results: Sedation scores of group M were higher than group P
and group F. Group P had a higher VRS score than group M and
group F at 30 min after extubation. Dose of additional fentanyl 50
μg injection was similar among three groups.
Conclusions: Fentanyl 50μg intravenous injection at the end of surgery with additional fentanyl 50μg injection on patient’s request
may be good method for early pain control for IV-PCA patients.
