Bupivacaine-fentanyl isobaric spinal anesthesia reduces the risk of ICU admission in elderly patients undergoing lower limb orthopedic surgery.

BACKGROUND: To evaluate if bupivacaine-fentanyl isobaric spinal anesthesia could reduce the risk of ICU admission compared with general anesthesia in elderly patients undergoing lower limb orthopedic surgery. METHODS: This study comprised a retrospective review of all lower limb orthopedic surgeries performed at our hospital between January 2013 and December 2019. According to anesthesia methods, patients were divided into the spinal anesthesia group (n = 1,728) and the general anesthesia group (n = 188). The primary outcome evaluated was the occurrence of ICU admission. Secondary outcomes included hemodynamic changes, postoperative complications, and mortality. RESULTS: Repeated measure analysis of variance indicated that the difference between the two groups in the systolic blood pressure (SBP) was not significant before anesthesia (T0), immediately after anesthesia (T1), and before leaving the operation room (T8) (P > 0.05), but significant (P < 0.01) from 5 min after anesthesia (T2) to after operation (T7). The proportions of ICU admission (6.4% vs. 23.8%, P < 0.01) and unplanned intubation (0.1% vs. 3.8%, P < 0.01) were significantly lower in the spinal anesthesia group compared with those in the general anesthesia group. Multivariate logistic regression revealed that after controlling for potential confounding factors, the odds of ICU admission for patients in the spinal anesthesia group was 0.240 times (95% CI 0.115-0.498; P < 0.01) than those in the general anesthesia group. CONCLUSIONS: Bupivacaine-fentanyl isobaric spinal anesthesia significantly reduced the risk of ICU admission and unplanned intubation, and provided better intraoperative hemodynamics in elderly patients undergoing lower limb orthopedic surgery. TRIAL REGISTRATION: This study has been registered in the Chinese Clinical Trial Registry (ChiCTR2000033411).

Analgesic Efficacy of an Ultrasound-Guided Transversus Thoracis Plane Block Combined with an Intermediate Cervical Plexus Block on Postoperative Pain Relief After Trans-Areolar Endoscopic Thyroidectomy: A Single Center Prospective Randomized Controlled Study.

Purpose: This study aimed to investigate the analgesic effect of ultrasound-guided transversus thoracis plane block (TTPB) combined with intermediate cervical plexus block (ICPB) in the early postoperative period after trans-areolar endoscopic thyroidectomy. Patients and Methods: A total of 62 female patients undergoing trans-areolar endoscopic thyroidectomy were randomly classified to the TTPB combined with ICPB group with ropivacaine (block group) or superficial cervical plexus block group (control group). The primary outcome measures were resting visual analogue scale (VAS) in the chest area at 6 h after surgery. The secondary outcome measures included chest resting and movement VAS score, neck resting and movement VAS score within 24 h after surgery, intraoperative remifentanil consumption, postoperative analgesia rate and analgesic requirements and patient satisfaction score for pain management at discharge. Results: Compared with the control group, the block group at rest showed consistently lower VAS scores in the chest area at 6 and 12 h after operation; the block group at rest showed lower VAS scores in the neck at 6, 12 and 24 h after operation. Regarding movement, the VAS scores of the chest and neck area at 2, 6, 12 and 24 h after the operation were lower in the block group than in the control group. The consumption of remifentanil, rate of postoperative analgesic requirements, and consumption of postoperative rescue analgesia in the block group were lower than those in the control group. Satisfaction with pain treatment at discharge was higher in the block group than in the control group. Conclusion: Ultrasound-guided TTPB combined with ICPB provides good analgesic effect in the early postoperative period after trans-areola endoscopic thyroidectomy.
