RESUMEN
Objective:To investigate the clinical effect of preemptive analgesia with pentazocine on perioperative pain management in partial splenectomy.Methods:A total of 100 patients with traumatic splenic rupture who underwent partial splenectomy at Yiwu Central Hospital between October 2019 and November 2021 were randomly assigned to either the control group or the study group, with 50 patients in each group using the random number table method. Both groups received patient-controlled analgesia postoperatively. Additionally, the study group received intravenous pentazocine administration before surgery. The amount of anesthetic used during surgery, postoperative anesthesia recovery indices, postoperative pain response, serum inflammatory factor levels, and the number of effective patient-controlled analgesia pump presses within 48 hours postoperatively were recorded and evaluated. Any adverse drug reactions were also monitored.Results:The dosages of propofol [(462.24 ± 27.13) mg] and remifentanil [(365.98 ± 26.78) μg] in the study group were significantly lower than those in the control group [(511.82 ± 26.32) mg, (406.86 ± 26.08) μg, t = 14.49, 12.63, both P < 0.001). The recovery time of spontaneous breathing [(6.86 ± 0.97) minutes], anesthesia recovery time [(13.24 ± 0.82) minutes] and extubation time [(17.14 ± 1.07) minutes] were significantly shorter than those in the control group [(7.62 ± 0.90) minutes, (14.32 ± 0.84) minutes, (18.22 ± 1.06) minutes, t = 5.80, 8.58, 6.93, all P < 0.001]. The Visual Analogue Scale (VAS) scores in the study group were significantly lower than those in the control group at 24 and 48 hours after surgery, both in resting and coughing state ( t = 7.82, 9.31, 4.95, 8.47, all P < 0.001). The serum levels of tumor necrosis factor-alpha, interleukin-1, and interleukin-6 were significantly lower in the study group than in the control group ( t = 21.53, 25.61, 18.45, 16.90, 17.33, 14.86, all P < 0.001), while the serum level of interleukin-10 was significantly higher in the study group than in the control group ( t = -20.85, -19.61, both P < 0.001). The number of effective patient-controlled pump analgesia presses within 48 hours postoperatively in the study group [(6.24 ± 1.17) times] was significantly lower than that in the control group [(10.26 ± 1.34) times, t = 12.95, P < 0.05). In addition, the overall incidence of adverse drug reactions in the study group [4.00% (2/50)] was significantly lower than that in the control group [18.00% (9/50), χ2 = 5.01, P < 0.05]. Conclusion:Preemptive analgesia with pentazocine for patients undergoing partial splenectomy can effectively reduce the dosage of anesthetics during surgery and the dosage of analgesics after surgery, enhance the recovery from postoperative anesthesia, suppress postoperative inflammatory reactions, alleviate pain responses, and minimize the risk of adverse drug reactions.
