Objectives: We sought to review findings from recent literature on the postresuscitation care of cardiac arrest patients using therapeutic hypothermia as part of nontrial treatment.
Design: Literature review.
Setting: Hospital-based environment.
Subjects: Patients initially resuscitated from cardiac arrest who underwent hypothermia induction as a treatment regimen or historical control patients who did not receive hypothermia therapy.
Measurement: : We compiled protocol methodology from the various studies, as well as survival-to-hospital discharge and neurological outcomes.
Main Results: Although varied in their protocols and outcome reporting, results from published investigations confirmed the findings from landmark randomized controlled trials, in that the use of therapeutic hypothermia increased survival with an odds ratio of 2.5 (95% confidence interval, 1.8-3.3) and favorable outcome with an odds ratio of 2.5 (95% confidence interval, 1.9-3.4).
Conclusions: The survival and neurological outcomes benefit from therapeutic hypothermia are robust when compared over a wide range of studies of actual implementation.

Risperidone-Induced Hypothermia in a Cerebral Palsy Patient: A Case Report and Literature Review.
Cureus

Internal Medicine, King Abdulaziz Specialist Hospital, Taif, SAU.
Cerebral palsy (CP) is a debilitating disorder that can lead to life-long disability, with a high incidence in Saudi Arabia. Secondary epilepsy and cardiac complications are common in CP patients. We present a rare case of a 17-year-old female with CP, attention-deficit hyperactivity disorder (ADHD), secondary epilepsy, and a history of post-cardiac arrest, with home medications carbamazepine, risperidone, and sodium valproate.

Background: Finding an accurate and simple method of thermometry in the neonatal intensive care unit is important. The temporal artery thermometer (TAT) has been recommended for all ages by the manufacturer; however, there is insufficient evidence for the use of TAT in infants, especially to detect hypothermia.
Purpose: To assess the accuracy of the TAT in hypothermic neonates in comparison to a rectal thermometer.

This study aimed to evaluate the hemodynamic and ventricular performance of neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia using conventional and advanced echocardiographic techniques. This observational, prospective study included 22 neonates with HIE matched with 22 healthy neonates. Echocardiographic studies were performed 24 h after achieving target temperature during hypothermia and 24 h after rewarming.

The effect of sex in outcomes after severe traumatic brain injury (TBI) remains uncertain. We explored whether outcomes differed between women and men after standardized care management during the first 5 days in the intensive care unit (ICU). This study was an observational analysis of the OXY-TC multicenter randomized clinical trial between June 15, 2016 and April 17, 2021.

Methionine sulfoximine (MSO) is a compound originally discovered as a byproduct of agene-based milled flour maturation. MSO irreversibly inhibits the astrocytic enzyme glutamine synthase (GS) but also interferes with the transport of glutamine (Gln) and of glutamate (Glu), and γ-aminobutyric acid (GABA) synthesized within the Glu/Gln-GABA cycle, in this way dysregulating neurotransmission balance in favor of excitation. No wonder that intraperitoneal administration of MSO has long been known to induce behavioral and/or electrographic seizures.
