Meta AnalysisIntraoperative Methadone Reduces Pain and Opioid Consumption in Acute Postoperative Pain: A Systematic Review and Meta-analysis.
Methadone is a potent opioid exerting an analgesic effect through N-methyl-D-aspartate receptor antagonism and the inhibition of serotonin and noradrenaline reuptake. It has also been used in several procedures to reduce postoperative pain and opioid use. This meta-analysis aimed to determine whether the intraoperative use of methadone lowers postoperative pain scores and opioid consumption in comparison to other opioids. ⋯ Intraoperative use of methadone reduced postoperative pain scores compared to other opioids, and Trial Sequential Analysis suggested that no more trials are required to confirm pain reduction at rest until 48 hours after surgery. Methadone also reduced postoperative opioid consumption and led to better patient satisfaction scores through 72 hours postoperatively compared to other opioids.

National Partnership for Maternal Safety Recommended Maternal Early Warning Criteria Are Associated With Maternal Morbidity.
Many cases of maternal mortality and morbidity are preventable. A delayed response to clinical warning signs contributes to preventability. Therefore, the National Partnership for Maternal Safety devised maternal early warning criteria (MEWC), composed of abnormal vital signs that trigger bedside evaluation by a provider with the capacity to escalate care. The relationship of the MEWC to maternal morbidity has not been studied. We evaluated the correlation between the MEWC and maternal morbidity. ⋯ The MEWC are associated with maternal morbidity. As a screening tool, they appropriately prioritize sensitivity and have an excellent negative predictive value. The criteria demonstrate low specificity, which is slightly improved by considering only patients with recurrent or multiple triggers. Additional efforts to improve the specificity of MEWC, with a focus on identifying sustained or recurrent patterns of abnormal vital signs, may be necessary before their widespread implementation.

ReviewDistribution of Extreme Vital Signs and Complete Blood Count Values of Healthy Parturients: A Retrospective Database Analysis and Review of the Literature.
The impact of physiological adjustments throughout pregnancy on maternal vital signs and laboratory values has yet to be fully defined. The present study was designed to determine the normal range of these parameters among healthy pregnant women during the peripartum period. ⋯ Our findings justify the practice of using ≥2 repeated measurements for diagnosing hypertensive disorders of pregnancy. Lower normal blood pressure limits may be below those defining hypotensive shock. Normal heart rates exceed the accepted definitions of both tachy- and bradycardia. Normal temperatures at all times have a more narrow range than previously thought, and the normal range of white blood cell count has outliers exceeding the current definitions of leukocytosis or leukopenia at all times. The normal lower range of hemoglobin was constantly below 10 g/dL, and normal platelet counts were considerably lower than those previously described. The vital signs and complete blood count values thus far considered normal for the peripartum period may require some adjustment. New definitions for hypotension, tachy- and bradycardia, fever, and leukocyte quantitative disorders should be considered.

Randomized Controlled TrialImpact of Local Infiltration Analgesia on the Quality of Recovery After Anterior Total Hip Arthroplasty: A Randomized, Triple-Blind, Placebo-Controlled Trial.
Local infiltration analgesia (LIA) is commonly used in anterior total hip arthroplasty (THA) surgery; however, evidence for its efficacy is lacking. We hypothesized that LIA with 0.2% ropivacaine when compared with injection of placebo (0.9% saline) would improve patient quality of recovery on postoperative day (POD) 1, as measured by the Quality of Recovery-15 (QoR-15) score. ⋯ LIA with 0.2% ropivacaine when compared with 0.9% saline as placebo did not improve quality of recovery 1 day after anterior THA.
