Thoracic epidural analgesia in a patient with von Hippel-Lindau disease.

von Hippel-Lindau disease (VHLD) is an autosomal dominant disorder characterized by central nervous system hemangioblastomas and renal tumors. Here, we report a case of thoracic epidural placement in a 35-year-old woman with VHLD presenting for left open heminephrectomy for renal masses. We also reviewed the literature on this topic.

Spinal Anesthesia or General Anesthesia for Hip Surgery in Older Adults.

BACKGROUND: The effects of spinal anesthesia as compared with general anesthesia on the ability to walk in older adults undergoing surgery for hip fracture have not been well studied. METHODS: We conducted a pragmatic, randomized superiority trial to evaluate spinal anesthesia as compared with general anesthesia in previously ambulatory patients 50 years of age or older who were undergoing surgery for hip fracture at 46 U.S. and Canadian hospitals. Patients were randomly assigned in a 1:1 ratio to receive spinal or general anesthesia. The primary outcome was a composite of death or an inability to walk approximately 10 ft (3 m) independently or with a walker or cane at 60 days after randomization. Secondary outcomes included death within 60 days, delirium, time to discharge, and ambulation at 60 days. RESULTS: A total of 1600 patients were enrolled; 795 were assigned to receive spinal anesthesia and 805 to receive general anesthesia. The mean age was 78 years, and 67.0% of the patients were women. A total of 666 patients (83.8%) assigned to spinal anesthesia and 769 patients (95.5%) assigned to general anesthesia received their assigned anesthesia. Among patients in the modified intention-to-treat population for whom data were available, the composite primary outcome occurred in 132 of 712 patients (18.5%) in the spinal anesthesia group and 132 of 733 (18.0%) in the general anesthesia group (relative risk, 1.03; 95% confidence interval [CI], 0.84 to 1.27; P = 0.83). An inability to walk independently at 60 days was reported in 104 of 684 patients (15.2%) and 101 of 702 patients (14.4%), respectively (relative risk, 1.06; 95% CI, 0.82 to 1.36), and death within 60 days occurred in 30 of 768 (3.9%) and 32 of 784 (4.1%), respectively (relative risk, 0.97; 95% CI, 0.59 to 1.57). Delirium occurred in 130 of 633 patients (20.5%) in the spinal anesthesia group and in 124 of 629 (19.7%) in the general anesthesia group (relative risk, 1.04; 95% CI, 0.84 to 1.30). CONCLUSIONS: Spinal anesthesia for hip-fracture surgery in older adults was not superior to general anesthesia with respect to survival and recovery of ambulation at 60 days. The incidence of postoperative delirium was similar with the two types of anesthesia. (Funded by the Patient-Centered Outcomes Research Institute; REGAIN ClinicalTrials.gov number, NCT02507505.).

Need for preoperative anemia management clinics in Japan: initiatives at a university hospital in the USA.

Untreated preoperative anemia increases the risk of morbidity and mortality and there is increasing evidence that early intervention for preoperative anemia improves outcomes after major surgery. Accordingly, anemia management clinics have been established in various institutions in the USA. As an example, the University of Iowa Hospitals and Clinics outpatient clinic treats pre-surgical anemic patients, who undergo major surgery with anticipated blood loss of more than 500 mL, by providing effective standardized care in a timely manner. This standardized care is an integral part of patient blood management to reduce perioperative blood transfusion and improve patient outcomes. The importance of preoperative anemia management has not yet been sufficiently recognized in Japan. Timely intervention for preoperative anemia should be incorporated into routine pre-surgical patient care in Japan.

Impact of paravertebral blocks on analgesic and non-analgesic outcomes after video-assisted thoracoscopic surgery: A propensity matched cohort study.

BACKGROUND: Regional analgesic techniques such as paravertebral blocks (PVBs) have been popularized for analgesia following video-assisted thoracoscopic surgery (VATS). In this single center retrospective propensity matched cohort of subjects, we investigate the impact of paravertebral blocks on the analgesic and non-analgesic outcomes. METHODS: Institutional database was queried to identify all patients undergoing VATS between January 2013 and July 2019 and these patients were divided into those who received paravertebral blocks in combination with general anesthesia (GA) [PVB group] and those who received GA without paravertebral blocks [GA group]. Propensity score matching based on common patient confounders were used to identify patients in each group. Primary outcomes of the study were average pain scores and opioid consumption in the first 24 hours. Secondary analgesic outcomes included pain scores and opioid requirements at other timepoints over the first 48 hours. Non analgesic outcomes were obtained from STS General Thoracic Surgery Database and included length of hospital stay, need for ICU admission, composite outcome of any complication during the hospital course and 30-day mortality. Exploratory analyses were conducted to investigate the impact of PVB on analgesia following different types of surgery and as to whether any other covariates had a greater influence on the included patient centered outcomes. MAIN RESULTS: After propensity score matching, a total of 520 patients (260 per group) were selected for the study out of 1095 patients. The opioid consumption in terms of oral morphine milligram equivalent (MME) [Median (IQR)] for the first 24 hours was significantly lower with the use of PVB [PVB group- 78.5 (96.75); GA group-127.0 (111.5); p<0.001] while the average pain scores in the first 24 hours did not differ significantly [PVB group-4.71 (2.28); GA group-4.85 (2.30); p = 0.70]. The length of hospital stay, opioid requirements at other timepoints, need for ICU admission in the immediate post-operative period and the composite outcome-'any complication' (35% vs 48%) were significantly lower with the use of PVB. Subgroup analysis showed a longer duration of benefit following major lung surgeries compared to others. CONCLUSION: Paravertebral blocks reduced the length of stay and opioid consumption up to 48 hours after VATS without significantly impacting pain scores.

A Case Report of Slowly Evolving Epidural Hematoma After Lumbar Drain Removal Following Initiation of Clopidogrel Therapy.

Guidelines on the management of lumbar drain in patients receiving antithrombotic therapy are lacking, with American Society of Regional Anesthesia and Pain Medicine (ASRA) anticoagulation guidelines for regional anesthesia providing the best possible guidance for this scenario. However, the risk-benefits of placing a lumbar drain in the context of vascular surgery differ from placement of neuraxial blockade. One of the changes included in the recently published ASRA guidelines is that clopidogrel can be started on a patient with an indwelling neuraxial catheter. We report a case of slowly evolving epidural hematoma following the initiation of clopidogrel therapy in a patient with an indwelling lumbar drain.

Comparison of the effect of three different adjuvants on the analgesic duration of single injection interscalene brachial plexus block: a prospective, randomized, triple blinded clinical trial.

BACKGROUND AND OBJECTIVES: Use of regional anesthesia can result in faster recovery and better patient satisfaction. Addition of perineural adjuncts to local anesthetics may improve the duration of analgesia, but there is a paucity of data comparing them in a single randomized trial. We compared the effects of three adjuncts clonidine, dexamethasone, and buprenorphine, on the duration of analgesia of interscalene brachial plexus block. METHODS: 160 patients, undergoing elective shoulder surgery, were randomized to four groups to receive an interscalene block with one of the following solutions: ropivacaine alone, ropivacaine with clonidine 75 µg, ropivacaine with dexamethasone 8 mg, or ropivacaine with buprenorphine 300 µg. The primary outcome variable was the duration of analgesia; secondary outcome measures were time to onset of the block, and the duration of sensory and motor blocks. RESULTS: There was no statistically significant difference in the total analgesia time among the four groups; p=0.11. The pairwise comparison in analgesic time and 99% CI were: control versus clonidine (-1.94 hours (-7.33 to 3.12)), control versus dexamethasone (-4.16 hours (-9.50 to 0.58)) and control versus buprenorphine (-1.1 hours (-5.34 to 3.23)). There was no differences in block set-up time, or total sensory and motor block duration among the groups. CONCLUSION: There was no significant improvement in the duration of analgesia with addition of any of the three adjuncts to interscalene blocks. However, there was a larger than expected variability in patient response, hence the study may have been underpowered for the primary outcome.

Fascia Iliaca Block for Reduction of Anterior Native Hip Dislocation: a Case Report.

Native hip dislocations require urgent reduction in a setting where adequate sedation and analgesia is essential. We have recently implemented the use of fascia iliaca blocks at our institution for preoperative pain management for patients with proximal femur fractures. In the setting of limited resources, alternate modalities for sedation and analgesia may need to be implemented to obtain a timely reduction for hip dislocations. We present a case report where of the use of a fascia iliaca block along with light sedation to obtain a successful, atraumatic reduction of an anterior dislocation of a native hip joint. While many hip dislocations may require a deeper level of sedation and muscle relaxation for successful reduction, the current report suggests that fascia iliaca blocks provide adequate analgesia for the procedure and may be helpful in the setting of limited resources.
