RESUMO
BACKGROUND: The efficacy of perioperative intravenous magnesium administration on postoperative opioid use, opioid-related side effects (e.g., nausea and vomiting) and pain are uncertain, as randomized controlled trials on this topic have reported disparate results. The objective of this systematic review is to determine if perioperative magnesium reduces opioid use, opioid-related side effects, and postoperative pain. METHODS: An electronic search was conducted using the Library of Medicine's PubMed and EMBASE databases. Included studies consisted of randomized controlled trials in an adult population with a clearly defined comparison of perioperative intravenous magnesium administration to a control with a documented assessment of opioid usage and postoperative pain. Relevant data was abstracted from included studies. Pooled estimates for weighted mean difference (WMD) with 95% confidence intervals (CI) were obtained for our primary outcome (opioid usage) using the Cochrane Collaboration's RevMan version 4.2.7 (Cochrane Collaboration; Oxford, United Kingdom). WMD and odds ratios (OR) were calculated using a random effects model. RESULTS: The literature search ultimately yielded 22 trials, enrolling 1177 (599 magnesium, 578 control) patients, who were included in the analysis. A significant decrease in morphine usage by those patients who received magnesium was noted (WMD = -7.40; 95% CI: -9.40 to -5.41, p < 0.00001). Perioperative magnesium administration was not associated with a difference in postoperative nausea or vomiting (RR = 0.76; 95% CI: 0.52 to 1.09, p = 0.14). The pooled visual analog scores for pain at 4-6 hours after surgery were significantly less in those patients who received magnesium surgery (WMD = -0.67; 95% CI: -1.12 to -0.23, p = 0.003); however, there was no difference in pain scores at 20-24 hours after surgery (WMD = -0.25; 95% CI: -0.62 to 0.71, p = 0.17). CONCLUSION: Based on the results of this systematic review, perioperative intravenous magnesium may be a useful adjuvant for the management of postoperative pain providing analgesia through a different mechanism of action than that of opioids and would make a potential addition to a multimodal anlgesic treatment plan; however, the decrease in opioid use with perioperative magnesium infusion does not appear to be associated with a decresea in opioid-related side effects.

INTRODUCTION: Asthma is one of the most common chronic diseases of childhood. There is a scarcity of published literature on critical asthma, considered acute asthma requiring pediatric intensive care unit (PICU) admission. The goal of this study was to describe the clinical care of children with critical asthma admitted to a single center PICU and to determine whether pulmonary medicine consultation during admission impacted outcomes. METHODS: Retrospective chart review of known asthma patients aged 4-18 years admitted to a quaternary PICU between 01/2013 and 07/2019 for management of critical asthma. RESULTS: A total of 179 patients were enrolled with median age of 8 years. Median hospital length of stay (LOS) was 3.2 days and PICU LOS was 1.5 days. A total of 80 (44.7%) patients had a pulmonary medicine consultation. In the pulmonary medicine consultation group versus the no-pulmonary medicine consultation group, there was a significant difference in hospital LOS (4.16 vs. 2.86 days, p value <.0001) and PICU LOS (2.00 vs. 1.00, p value <.0001), escalation of controller medication (66% vs. 21%, p value <.0001), scheduled outpatient pulmonology follow-up (87.5% vs. 45.4%, p value <.0001), and receiving ≥3 courses of systemic steroids in the 12 months after discharge (32.2% vs. 14.7%). There was no difference in attendance of scheduled follow up appointments or in having ≥3 emergency room visits or admissions in the 12 months after discharge. CONCLUSION: Pulmonary medicine consultation during hospital admission may impact management of critical asthma by increasing escalation of controller medication and scheduled outpatient follow up.

Background and Purpose: The use of extracorporeal membrane oxygenation (ECMO) has been described for near-fatal asthma that continues to be refractory despite maximal medical therapy. Methods: Patients admitted to the pediatric intensive care unit at Texas Children's Hospital from 2012 to 2020 with the diagnosis of asthma who were supported on ECMO or isoflurane were included in the study. Patient demographics, medication usage, and complications were compared between the case group (ECMO, n = 12) and the control group (isoflurane only, n = 8). Results: All patients survived to discharge. ECMO patients received shorter durations of albuterol (12 versus 104 h, P = 0.0002) and terbutaline (13.3 versus 31.5 h, P = 0.0250). There were no differences in complication rates between the 2 groups. Conclusion: ECMO is a reasonable and safe support method for patients with near-fatal asthma and may lead to less bronchodilator medication exposure when compared with inhaled volatile anesthetic use.
