Comparison of Lumbar Epidurals and Lumbar Plexus Nerve Blocks for Analgesia Following Primary Total Hip Arthroplasty: A Retrospective Analysis.

BACKGROUND: Total hip arthroplasty (THA) is associated with significant postoperative pain. Both lumbar epidurals and lumbar plexus nerve blocks have been described for postoperative pain control, but it is unclear if one technique is more beneficial. METHODS: Using electronic medical records, a randomly selected, cohort of 58 patients with lumbar epidurals were compared with 58 patients with lumbar plexus nerve blocks following primary THA. The primary end point was 48-hour postoperative opiate consumption. Secondary end points included time of first ambulation, distance ambulated, level of assistance with ambulation, presence of side effects, and time to discharge. Descriptive statistics were calculated to characterize subjects in the different block-type groups. Comparisons in morphine consumption were conducted using linear mixed models. Primary and secondary end points were examined in multivariable models. RESULTS: Patients with lumbar plexus blocks consumed less opiates at 24, 36, and 48 hours relative to patients that received lumbar epidural catheters (P = .047, .002, and .002, respectively). Patients with lumbar plexus blocks ambulated earlier (24.6 ± 2.01 hours vs 31.7 ± 3.01 hours) and farther relative to patients with epidurals (P < .001 for both) and had discharge orders written earlier (58.2 ± 6.68 hours vs 73.6 ± 6.35 hours). CONCLUSION: In comparison to lumbar epidural catheters, lumbar plexus nerve blocks are an effective pathway for postoperative pain control following primary THA. Furthermore, this clinical pathway expedites physical rehabilitation and is more compatible with postoperative prophylactic anticoagulants.

Intraoperative goal-directed hemodynamic management in free tissue transfer for head and neck cancer.

BACKGROUND: The purpose of this study was to determine the effect of algorithmic physiologic management on patients undergoing head and neck free tissue transfer and reconstruction. METHODS: Ninety-four adult patients were randomized to treatment and control groups. The blood pressure of the control group was managed consistent with contemporary standards. The treatment group was managed using an algorithm based on blood pressure and calculated physiologic values derived from arterial waveform analysis. Primary outcome was intensive care unit (ICU) length of stay. RESULTS: ICU length of stay was decreased in the treatment group (33.7 vs 58.3 hours; p = .026). The complication rate was not increased in the treatment group. CONCLUSION: The goal-directed hemodynamic management algorithm decreased the ICU length of stay. Judicious use of vasoactive drugs and goal-directed fluid administration has a role in improving perioperative outcomes for patients undergoing head and neck free tissue transfer. © 2016 Wiley Periodicals, Inc.

Vital signs and demographics in the preparticipation sports exam: do they help us find the elusive athlete at risk for sudden cardiac death?

Much attention recently has been paid to the detection of those young athletes who may be at risk for sudden cardiac death (SCD) in sports participation. In this article, we attempt to summarize the remarkably few studies that examine the question of whether vital signs and basic demographics are associated with athletes at risk for SCD. Historical items such as chest pain, dyspnea, and palpitations are not reviewed. The only demographics mentioned in the literature as associated with SCD are being of the male gender, which is associated highly with SCD, and being African-American. Most notably, we were unable to find even prospective data asking the question of whether resting pulse, blood pressure, height, weight, and age are potential risk factors. Therefore, we also have included recent data from our own research to make this summary more complete.
