[Application of superior iliac fascia block of inguinal ligament combined with patient controlled intravenous analgesia in elderly patients after hip arthroplasty].

OBJECTIVE: To compare the effect of patient-controlled intravenous analgesia(PCIA) and superior inguinal ligament iliac fascia block combined with PCIA after hip replacement in the elderly. METHODS: Total of 82 elderly patients were treated with hip arthroplasty from June 2019 to June 2021 and randomly divided into observation group and control group. There were 42 patients in control group, including 18 males and 24 females, aged from 60 to 78 years old with an average of (70.43±3.67) years old, 28 femoral neck fractures and 14 femoral head necrosis, who received PCIA. The study group consisted of 42 cases, including 20 males and 22 females, aged from 61 to 76 years old with an average of (69.68±3.74) years old, 25 femoral neck fractures and 17 femoral head necrosis, who received superior inguinal ligament iliac fascia block combined with PCIA. Pain visual analogue scale (VAS) and Ramesay sedation scores at 2 h, 6 h, 12 h, 24 h and 48 h after operation were evaluated. In addition, the follow-up results of the total consumption of sufentanil and the total number of PCIA compressions at 48 hours after operation, the first time of landing after surgery, the time of hospital stay, the incidence of adverse reactions, the satisfaction with analgesia of two groups were observed. RESULTS: All patients were followed up for 9 to 24 months with an average of(13.85±2.67) months. There was no significant difference in operation time and intraoperative bleeding between two groups (P>0.05). There was no difference in VAS between two groups at 2 hours after operation (P>0.05), and the VAS of the study group at 6 h, 12 h, 24 h and 48 h after operation were lower than those of the control group(P<0.05). The Ramesay sedation scores of the study group at 2 h, 6 h and 12 h after operation were higher than those of the control group(P<0.05), and there were no differences in Ramesay score between two groups at 24 h and 48 h after operation (P>0.05). The consumption of sufentanil in the study group within 48 hours after operation was lower than that in the control group (P<0.05), and PCIA compression times were lower than those in the control group(P<0.05), and the time of first landing was earlier than that in the control group(P<0.05). There was no significant difference in hospital stay, adverse reaction rate, complications between two groups (P>0.05). The satisfaction of analgesia in the study group was higher than that in the control group (P<0.05). CONCLUSION: Superior iliac fascia block of inguinal ligament combined with PCIA has significant analgesic and sedative effects after hip arthroplasty in the elderly. It can reduce the amount of sufentanil used and the total number of PCIA compressions, which is conducive to the early activity of patients out of bed, improve the satisfaction of analgesia.

Effects of ultrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia on the anesthetic efficacy and surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery: a randomized controlled trial.

BACKGROUND: Surgery for intertrochanteric fractures in elderly patients is challenging due to the risk of severe pain and significant stress responses. We investigated the effects of a combined approach of ultrasound-guided lumbar plexus and sacral plexus block with general anesthesia on anesthetic efficacy and surgical outcomes in these patients. METHODS: A randomized controlled trial was conducted involving 150 elderly patients, divided into two groups: the combined anesthesia group (receiving ultrasound-guided lumbar plexus and sacral plexus block along with general anesthesia) and the general anesthesia alone group. Outcome measures included hemodynamic parameters, postoperative pain levels (VAS scores), postoperative recovery times, and incidence of adverse reactions. RESULTS: In the combined anesthesia group, the patients had more stable intraoperative hemodynamics, lower postoperative VAS scores at 1, 3, and 6 h, and faster recovery times (eye-opening upon command and return of respiratory function) compared to the general anesthesia group. Furthermore, the incidence of adverse reactions was significantly lower in the combined anesthesia group. CONCLUSIONS: Ultrasound-guided lumbar plexus and sacral plexus block combined with general anesthesia enhanced the anesthetic efficacy and improved surgical outcomes in elderly patients undergoing intertrochanteric fracture surgery.

Acupuncture Therapy Fully Improves the Heart Rate Variability Indexes of Elderly Patients with Fractures.

Objective: To investigate the effect of acupuncture on perioperative heart rate changes in elderly patients with hip or femur fractures undergoing surgery. Methods: A total of 120 patients with hip or femur fractures aged over 70 years and ASA ≥ II were selected for selective fracture osteotomy and reduction with internal fixation or arthroplasty. They were divided into Group H and Group N according to whether they suffering from comorbidities, and then divided into the HS group (complication group), HD group (complication control group), NS group (without complication group), and ND group (without complication control group) (n = 30). Patients received acupuncture therapy at bilateral Neiguan and Zusanli acupoints before anesthesia on the first and second days after surgery. They were also subjected to 24-h dynamic electrocardiogram (ECG) monitoring before surgery and on the third day after surgery. Blood pressure, heart rate, SPO2, and cardiac oxygen consumption after acupuncture were recorded. SDNN and Triangular Index were recorded. Results: The systolic blood pressure and myocardial oxygen consumption in the H group were significantly lower than those in the N group (P < .05). In addition, SDNN and Triangular Index in the HS group were increased after the operation when compared with those before the operation (P < .05). Postoperative INDEXES of SDNN and Triangular in the HS group and HD group were lower than those in the NS group and ND group before surgery (P < .05), while the postoperative indexes of SDNN and Triangular in the HD group were lower than those in HS group, NS group and ND group (P < .05). Conclusion: Our study preliminarily revealed the perioperative efficacy of electroacupuncture at Neiguan and Zusanli acupoints: In conclusion, electroacupuncture at Neiguan and Zusanli acupoints demonstrates promise in improving perioperative safety and reducing cardiovascular adverse reactions in elderly patients with fractures undergoing surgery.

OBJECTIVES: To observe the efficacy of electroacupuncture (EA)combined with continuous adductor canal block (CACB)for postoperative analgesia in patients undergoing total knee arthroplasty (TKA), and to explore its effect on pain factor levels. METHODS: Eighty-two patients with knee osteoarthritis undergoing unilateral TKA were randomly divided into an observation group and a control group, with 41 patients in each group. The patients in the control group were treated with CACB under ultrasound guidance on the affected side after removal of the endotracheal tube. In the observation group, electroacupuncture therapy was added on day 1-7 after operation; the acupoints included Hegu (LI 4), Zusanli (ST 36), Taichong (LR 3), Taixi (KI 3), Yinlingquan (SP 9)and Yanglingquan (GB 34), with disperse-dense wave, in frequency of 1 Hz/30 Hz, 30 min each session, once a day. The knee joint range of motion was compared between the two groups before operation and on postoperative day 1, 3, 7, and 14. The pain visual analog scale (VAS)scores were compared 6, 12, 24, and 48 h after operation. The number of times that the pain pump was pressed within 48 h after operation and the number of remedial analgesia were also compared. Serum levels of prostaglandin E2 (PGE2)and ß-endorphin (ß-EP)were measured preoperatively and at 6, 12, 24, and 48 h after operation. Adverse reaction rates within 48 h after operation were documented. RESULTS: On postoperative day 1, 3, and 7, the observation group exhibited greater knee joint range of motion than that in the control group (P<0.05). At 6, 12, 24, and 48 h after operation, VAS scores at rest and during activity in the observation group were lower than those in the control group (P<0.05). The observation group had lower numbers of pain pump use and remedial analgesia within 48 h after operation than those in the control group (P<0.05). Serum PGE2 levels were lower in the observation group at 6, 12, and 24 h after operation (P<0.05), while serum ß-EP levels were higher (P<0.05) than those in the control group. There was no statistical difference in the incidence of adverse reactions within 48 h after operation between the two groups (P>0.05). CONCLUSIONS: EA therapy could enhance the analgesic effect of CACB in TKA patients, possibly by decrease the content of PGE2 and increase the content of ß-EP, with a high level of safety.

Pulmonary edema following shoulder arthroscopy under general anesthesia with nerve block: An observational study.

ABSTRACT: Shoulder arthroscopy requires a large of irrigation for a better surgical view, leading circulatory overload. This study was performed to prove whether pulmonary edema will be lead by a large of irrigation.General anesthesia with interscalene block was induced before operation. The primary outcome was ultrasound evaluation of B lines from the time before nerve block to the time 10 hours after operation. The secondary outcomes included oxygenation index, arterial partial pressure of carbon dioxide, visual analogue scale, muscle strength grade.A total of 93 patients were evaluated. Before surgery, B lines failed to be detected. While the highest total incidence of B lines was 49.4%, occurred at 4 hours after surgery. The highest incidences of severe and moderate pulmonary edema were 3.2% (P = .081) and 9.7% (P = .002), respectively. B lines were also found on both the affected and healthy side. During operation, the incidence of type 1 respiratory failure was 5.4% (P = .023) and that of both type 1 and 2 respiratory failure were 6.5% (P = .013). Pain was relieved in 6 hours after surgery (VAS < 3). At 12 hours after operation, the VAS of resting and motion were 4.68 ±â€Š2.27, 6.90 ±â€Š2.43, respectively. While the grade of muscle strength was 4.48 ±â€Š0.51 at 12 hours after operation.There is a high incidence of pulmonary edema in shoulder arthroscopy, and ultrasound is a convenient tool to evaluate this complication. Pain is relieved in 6 hours after surgery by nerve block. While muscle strength can also recover at 12 hours after surgery.

Ultrasound to guide the individual medical decision by evaluating the gastric contents and risk of aspiration: A literature review.

Pulmonary aspiration of gastric contents is one of the most terrible complications following general anesthesia. It is important for patients to prevent this complication by obeying the preoperative fasting protocol strictly. At present, it has been reported by many studies that bedside ultrasound, as a non-invasive and convenient method, could be used to evaluate gastric contents qualitatively and quantitatively. With the advantages of reliability, accuracy and repeatability, it can greatly reduce the risk of aspiration and ensure patients' life security. But most of the data were acquired from the healthy volunteers. For the gastrointestinal disorder, the pregnant women, obesity, children, the elderly and diabetes patients, the accuracy and reliability of ultrasound to predict the risk of aspiration remains to be identified by more further studies. For these patients with increasing risk of aspiration, I-AIM (Indication, Acquisition, Interpretation, Medical decision-making) framework plays an important role in ensuring the safety of patients. It is crucial to make appropriate clinical decisions by evaluating the gastric contents with ultrasound.
