Importance: There is limited information about the effect of erythropoietin or a high hemoglobin transfusion threshold after a traumatic brain injury.Objective: To compare the effects of erythropoietin and 2 hemoglobin transfusion thresholds (7 and 10 g/dL) on neurological recovery after traumatic brain injury.Design, Setting, and Participants: Randomized clinical trial of 200 patients (erythropoietin, n = 102; placebo, n = 98) with closed head injury who were unable to follow commands and were enrolled within 6 hours of injury at neurosurgical intensive care units in 2 US level I trauma centers between May 2006 and August 2012. The study used a factorial design to test whether erythropoietin would fail to improve favorable outcomes by 20% and whether a hemoglobin transfusion threshold of greater than 10 g/dL would increase favorable outcomes without increasing complications. Erythropoietin or placebo was initially dosed daily for 3 days and then weekly for 2 more weeks (n = 74) and then the 24- and 48-hour doses were stopped for the remainder of the patients (n = 126). There were 99 patients assigned to a hemoglobin transfusion threshold of 7 g/dL and 101 patients assigned to 10 g/dL.Interventions: Intravenous erythropoietin (500 IU/kg per dose) or saline. Transfusion threshold maintained with packed red blood cells.Main Outcomes and Measures: Glasgow Outcome Scale score dichotomized as favorable (good recovery and moderate disability) or unfavorable (severe disability, vegetative, or dead) at 6 months postinjury.Results: There was no interaction between erythropoietin and hemoglobin transfusion threshold. Compared with placebo (favorable outcome rate: 34/89 [38.2%; 95% CI, 28.1% to 49.1%]), both erythropoietin groups were futile (first dosing regimen: 17/35 [48.6%; 95% CI, 31.4% to 66.0%], P = .13; second dosing regimen: 17/57 [29.8%; 95% CI, 18.4% to 43.4%], P < .001). Favorable outcome rates were 37/87 (42.5%) for the hemoglobin transfusion threshold of 7 g/dL and 31/94 (33.0%) for 10 g/dL (95% CI for the difference, -0.06 to 0.25, P = .28). There was a higher incidence of thromboembolic events for the transfusion threshold of 10 g/dL (22/101 [21.8%] vs 8/99 [8.1%] for the threshold of 7 g/dL, odds ratio, 0.32 [95% CI, 0.12 to 0.79], P = .009).Conclusions and Relevance: In patients with closed head injury, neither the administration of erythropoietin nor maintaining hemoglobin concentration of greater than 10 g/dL resulted in improved neurological outcome at 6 months. The transfusion threshold of 10 g/dL was associated with a higher incidence of adverse events. These findings do not support either approach in this setting.Trial Registration: clinicaltrials.gov Identifier: NCT00313716. [ABSTRACT FROM AUTHOR]

Importance: The opioid epidemic has reignited interest in opioid-sparing strategies in managing pain. However, few studies have focused on opioid use during perioperative care in patients undergoing head and neck surgery with free flap reconstruction., Objectives: To examine the association between multimodal analgesia (MMA) administration and perioperative opioid requirements in patients undergoing head and neck surgery with free flap reconstruction and to investigate whether MMA alters the duration of stay in the postanesthesia care unit (PACU)., Design, Setting, and Participants: In this retrospective case-control study, data were collected between April 1, 2016, and December 31, 2017. The study was conducted at a single cancer center in the United States. Participants were 357 patients 18 years or older scheduled for head and neck surgery with free flap reconstruction., Exposures: Patients in the treatment group received oral celecoxib, gabapentin, and/or tramadol hydrochloride before surgery. Control group patients did not receive any of these medications., Main Outcomes and Measures: The amount of opioid administered in the operating room and in the PACU was converted to morphine equivalent daily dose (MEDD) for comparison between the 2 groups. The duration of stay in the PACU was based on the start time and end time of PACU care recorded by nurses in the PACU., Results: In total, 149 patients (mean [SD] age, 60.3 [13.7] years; 104 [69.8%] men) were included in the treatment group, and 208 patients (mean [SD] age, 64.2 [13.6] years; 146 [70.2%] men) were included in the control group. The mean (SD) MEDD of opioid given during surgery was 51.7 (19.8) in the treatment group and 67.9 (24.7) in the control group, for a difference in the means (treatment vs control) of -16.17 (95% CI, -20.81 to -11.52). In the PACU, the mean (SD) MEDD of opioid given was 11.7 (13.3) in the treatment group and 14.9 (15.7) in the control group, for a difference in the means (treatment vs control) of -3.22 (95% CI, -6.40 to -0.03). The MMA treatment remained largely associated with reduced amount of opioid given during surgery, in the PACU, and both combined after controlling for other important factors., Conclusions and Relevance: This case-control study found that the patients who received MMA before head and neck surgery with free flap reconstruction required less opioid medication. The treatment group also had shorter duration of stay in the PACU compared with the control group.
