Primary immune thrombocytopenia (ITP) is an autoimmune condition affecting women of childbearing age that is characterized by diminished platelet quantity with preserved function. Although pregnant women with ITP are often denied obstetric neuraxial anesthesia (OBNA) with low platelet counts for fear of neuraxial hematoma, the true magnitude of neuraxial hematoma for ITP parturients is unknown. The aim of this systematic review and meta-analysis was to examine OBNA outcomes in ITP parturients with platelet counts below 100 x 109·L-1. ⋯ Our study highlights continued reluctance to offer OBNA below the commonly quoted 80 x 109·L-1 platelet count, based largely on consensus and theoretical presumption of risk. This further negatively influences the accrual of large-scale data. The evidence of no neuraxial hematoma after OBNA provided herein offers support for considering neuraxial anesthesia at lower platelet count thresholds. Each patient should be afforded individualized discussion of risk and benefit relative to other analgesic measures.

Meta Analysis
Lidocaine lubricants for intubation-related complications: a systematic review and meta-analysis.
Postoperative sore throat (POST) is a relatively common morbidity. Topical lidocaine lubricants have been proposed to prevent POST; however, their effectiveness remains uncertain. This meta-analysis aimed to evaluate the prophylactic effect of lidocaine lubrications against POST, cough, and hoarseness in adult patients after surgery. ⋯ Lidocaine lubricants applied on the tips of endotracheal tube are not effective against the morbidities of POST, PC, and PH.

Tranexamic acid (TXA) reduces perioperative blood loss and transfusion requirement following cardiac surgery. Nevertheless, TXA remains underutilized because of concerns regarding development of adverse events. We conducted a systematic review to determine which patients are commonly excluded from TXA cardiac surgery clinical trials to determine if there are patient groups lacking safety data on TXA. ⋯ We found that systemic TXA is safe to use in cardiac surgery. Certain patient groups are frequently excluded from TXA cardiac surgery trials, and may consequently have limited efficacy and safety data on TXA. Further research in these patient groups may be needed; nevertheless, for many patient populations there are sufficient data to inform evidence-based guidelines for TXA use in cardiac surgery.

Postoperative sore throat negatively affects patient satisfaction and recovery. We conducted a systematic review and meta-analysis to examine the efficacy of preoperative topical administration of magnesium sulfate in preventing postoperative sore throat in adult patients. ⋯ Our study suggests that preoperative topical magnesium can effectively prevent postoperative sore throat.

Meta Analysis
Postoperative shared-care for patients undergoing non-cardiac surgery: a systematic review and meta-analysis.
Collaborative ("shared-care") models of postoperative care improve outcomes in patients undergoing surgery for hip fracture. Despite being widely adopted, it is unclear if similar benefits of shared-care models exist for other at-risk surgical patient populations. Thus, we performed a systematic review to understand the impact of shared-care models. ⋯ PROSPERO (CRD42018094943); registered 16 May, 2018.
