Reducing breakthrough pain during labour epidural analgesia: an update.
Curr Opin Anaesthesiol. 2019 Jun;32(3):307-314. doi: 10.1097/ACO.0000000000000713.
Abstract
Tan HS1, Sng BL1,2, Sia ATH1,2.
PURPOSE OF REVIEW: Neuraxial techniques are the current gold standard for labour analgesia, but are associated with up to 25% incidence of breakthrough pain. In this review, we aim to update clinicians on the latest research pertaining to the optimization of neuraxial labour analgesia. RECENT FINDINGS: Attempts to improve the efficacy and reliability of epidural analgesia while minimizing adverse effects have resulted in the rising popularity of combined spinal epidural and the dural puncture epidural (DPE). Recent studies have focused on determining the safety, efficacy, and optimization of the DPE technique.Another research focus is on the development of individualized therapy in which patients may titrate their own labour analgesia according to their varying requirements, possibly augmented with computer-aided feedback systems and automated mandatory bolus techniques that automatically adjust drug delivery to the patients' analgesic requirements. The addition of a risk-stratification model based on maternal, anaesthetic, and obstetric factors will facilitate early institution of individualized therapy to forestall breakthrough pain in higher risk patients. SUMMARY: Recent advances in combined spinal epidural, DPE, automated mandatory bolus, and individualized therapies have advanced our goal of providing effective labour analgesia that is titrated to changing analgesic requirements during labour and delivery and reducing breakthrough pain.

What's New in Obstetric Anesthesia? The 2017 Gerard W. Ostheimer Lecture.
Anesth Analg. 2019 Jul;129(1):168-175. doi: 10.1213/ANE.0000000000004188.
Abstract
Habib AS1.
The "What's New in Obstetric Anesthesia Lecture" is presented every year at the annual meeting of the Society for Obstetric Anesthesia and Perinatology. This lecture was established in 1975 to update the membership on the most relevant articles that were published in the preceding calendar year. In 1995, the lecture was renamed as the "Ostheimer Lecture" in honor of Gerard W. Ostheimer, an obstetric anesthesiologist from the Brigham and Women's Hospital with significant contributions in the field. This review summarizes key articles published in 2017 that were presented in the 2018 Ostheimer Lecture with a focus on opioid prescriptions, anesthesia for external cephalic version, labor analgesia, maternal morbidity, and global health. A proposed list of action items based on the 2017 literature is also presented.

Hyperventilation in neurological patients: from physiology to outcome evidence.
Curr Opin Anaesthesiol. 2019 Jun 18. doi: 10.1097/ACO.0000000000000764.
Abstract
Zhang Z1, Guo Q1, Wang E1,2.
PURPOSE OF REVIEW: Hyperventilation is commonly used in neurological patients to decrease elevated intracranial pressure (ICP) or relax a tense brain. However, the potentially deleterious effects of hyperventilation may limit its clinical application. The aim of this review is to summarize the physiological and outcome evidence related to hyperventilation in neurological patients. RECENT FINDINGS: Physiologically, hyperventilation may adversely decrease cerebral blood flow (CBF) and the match between the cerebral metabolic rate and CBF. In patients with severe traumatic brain injury (TBI), prolonged prophylactic hyperventilation with arterial carbon dioxide tension (PaCO2) less than 25 mmHg or during the first 24 h after injury is not recommended. Most patients (>90%) with an aneurysmal subarachnoid hemorrhage undergo hyperventilation (PaCO2 <35 mmHg); however, whether hyperventilation is associated with poor outcomes in this patient population is controversial. Hyperventilation is effective for brain relaxation during craniotomy; however, this practice is not based on robust outcome evidence. SUMMARY: Although hyperventilation is commonly applied in patients with TBI or intracranial hemorrhage or in those undergoing craniotomy, its effects on patient outcomes have not been proven by quality research. Hyperventilation should be used as a temporary measure when treating elevated ICP or to relax a tense brain. Outcome research is needed to better guide the clinical use of hyperventilation in neurological patients.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Sedation and Analgesia for Mechanically Ventilated Patients in the Emergency Department.
Emerg Med Clin North Am. 2019 Aug;37(3):545-556. doi: 10.1016/j.emc.2019.04.004.
Abstract
Noel C1, Mallemat H2.
Mechanically ventilated patients can experience significant pain and anxiety associated with their care. These symptoms should be aggressively treated, but can be challenging to manage without a systematic approach. This article reviews recent literature, current guidelines, and best practices in managing pain, agitation, and anxiety in mechanically ventilated patients in the emergency department.
