Abstract:
Objective:To investigate the analgesic effect of ultrasound-guided pericapsular nerve group (PENG) block combined with laryngeal mask general anesthesia and internal fixation of proximal femoral nail antirotation (PFNA) under ERAS concept in elderly patients.Methods:A total of 50 elderly patients with femoral trochanteric fractures treated with PFNA internal fixation who were admitted to Changsha Central Hospital from January 2021 to March 2022 were selected and according to the random number table method, they were divided into groups P and F, with 26 cases in group P (ultrasound-guided PENG block combined with laryngeal mask general anesthesia group) and 24 cases in group F [ultrasound-guided fascia iliaca compartment block (FICB)] combined with laryngeal mask general anesthesia group]. The bispectral index (BIS) of the two groups of patients was maintained within the range of 40-60, and the dosage of cyclopofol and remifentanil was adjusted according to the BIS and hemodynamic changes. Postoperative oxycodone was used for patient controlled intravenous analgesia (PCIA). When the Visual Analogue Scale (VAS) score ≥4, 1 mg intravenous oxycodone was administered as rescue analgesia. The VAS score was observed and recorded before nerve block (T 0), 10 minutes after nerve block (T 1), 20 minutes after nerve block (T 2), when the patients were placed in body position after bed (T 3), after laryngeal mask removal (T 4), 12 h after operation (T 5), 24 h after operation (T 6) and 48 h after operation (T 7). The mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SpO 2) at each time point from T 0 to T 4 were observed and recorded; the intraoperative dose of remifentanil, the rescue dose of oxycodone at postoperative T 6 and T 7, Lovett muscle strength score, anesthesia operation time, anesthesia recovery time and postoperative anesthesia-related complications were recorded. Results:There was no significant difference between the two groups in VAS scores at T 0, T 4, T 5 and T 6, MAP, HR and SpO 2 at T 0, T 1, T 2 and T 4, the dosage of remifentanil during operation, the remedial dosage of oxycodone at T 6 after operation, anesthesia operation time and anesthesia recovery time (all P>0.05). Compared with group F, the VAS scores of group P at T 1, T 2, T 3 and T 7 were lower than those of group F (all P<0.05); At T 3, there was no significant difference in SpO 2 between the two groups ( P>0.05), but the MAP and HR in group P was lower than that in group F (all P<0.05); The remedial dose of oxycodone at T 7 in group P was lower than that in group F ( P<0.05), and the analgesic effect was longer; Lovett muscle strength score at T 6 and T 7 in group P was better than that in group F (all P<0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusions:Compared with FICB, ultrasound-guided PENG block used in PFNA internal fixation in elderly patients has faster effect, lower dosage of opioid analgesics, longer duration of analgesia, and less impact on postoperative lower limb muscle strength.
