Objectives: The aim was to compare the feasibility of ultrasoundguided multiple nerve blocks (fascia iliaca compartment block+ sacral plexus block+superior cluneal nerve block) with general anesthesia in geriatric hip fracture patients.Methods: Ninety-four patients were randomly divided into 2 groups: group N received ultrasound-guided multiple nerve blocks and group G received general anesthesia. Primary outcome measures included perioperative Pain Threshold Index (PTI) and Numerical Rating Scale. Secondary outcome measures comprised the following: (1) perioperative Delirium Index and Short Portable Mental Status Questionnaire; (2) perioperative Comfort Index; (3) perioperative opioid consumption (within 72 hours postoperatively); and (4) postoperative side effects (within 72 h postoperatively).Results: Eighty-seven patients completed the study. Baseline PTI was comparable between the groups. However, intraoperative PTI was significantly lower in group N than in group G. Preoperative and postoperative Comfort Index scores were comparable between the groups. Moderate delirium (24 to 72 h postoperatively) was significantly higher than the baseline in group G. Early moderate delirium (24 h postoperatively) was significantly higher in group G than in group N. Severe delirium was comparable between the groups and within each group. High intraoperative PTI was associated with high opioid consumption. The intravenous sufentanil dose in group G was twice of that in group N. Incidence of nausea and vomiting was similar between the groups.Discussion: Ultrasound-guided multiple nerve blockade may be an alternative to the common anesthetic procedures used for geriatric hip fracture patients. It provided satisfactory intraoperative pain management and reduced early postoperative cognitive disorders.
Effect of dexmedetomidine on the cognitive function of patients undergoing gastric cancer surgery by regulating the phosphoinositide 3-kinase (PI3K)/AKT signaling pathway was investigated. A total of 110 patients who were diagnosed and underwent radical gastrectomy in Ruijin Hospital North,
Background Deep neuromuscular blockade may be beneficial on surgical space conditions during laparoscopic surgery. The effects of moderate neuromuscular blockade combined with transverse abdominal plane block (TAPB) on surgical space conditions during laparoscopic surgery have not been described. This work investigated whether the above combination is associated with similar surgical space conditions to those of deep neuromuscular blockade. Methods Eighty patients undergoing elective laparoscopic surgery for colorectal cancer were randomly divided into two groups. The intervention group was treated with moderate neuromuscular blockade (train-of-four (TOF) count between 1 and 3) combined with TAPB (M group), while the control group was treated with deep neuromuscular blockade (D group), with a TOF count of 0 and a post-tetanic count (PTC) ≥1. Both groups received the same anesthesia management. The distance between the sacral promontory and the umbilical skin during the operation was compared between the two groups. The surgeon scored the surgical space conditions according to a five-point ordinal scale. Patients’ pain scores were evaluated 8 h after the operation. Results The distance from the sacral promontory to the umbilical skin after pneumoperitoneum was similar between the D group and M group (16.03 ± 2.17 cm versus 16.37 ± 2.78 cm; P = 0.544). The 95% confidence intervals of the difference in the distance from the sacral promontory to the umbilical skin between the two groups were − 1.45–0.77 cm. According to the preset non-inferior standard of 1.5 cm, (− 1.45, ∞) completely fell within (− 1.50, ∞), and the non-inferior effect test was qualified. No significant difference was found in the surgical rating score between the two groups. The dosage of rocuronium in the group D was significantly higher than that in the group M (P < 0.01). The M group had significantly lower pain scores than the D group 8 h after the operation (P < 0.05). Conclusions Moderate neuromuscular blockade combined with TAPB applied to laparoscopic colorectal cancer surgery can provide surgical space conditions similar to those of deep neuromuscular blockade. In addition, it reduces the use of muscle relaxants, relieves postoperative pain within 4 h after operation, and shorten the extubation time and stay in PACU when neostigmine was used as muscle relaxant antagonist.
