Observational StudyMonitoring persistent pulmonary hypertension of the newborn using the arterial to end tidal carbon dioxide gradient.
Persistent pulmonary hypertension of the newborn (PPHN) can be monitored theoretically by the difference of the partial pressure of arterial (PaCO2) to end-tidal CO2 (EtCO2). We aimed to test the hypothesis that the PaCO2-EtCO2 gradient in infants with PPHN would be higher compared to infants without PPHN. Prospective, observational study of term-born ventilated infants with echocardiographically-confirmed PPHN with right-to-left shunting and term-born control infants without respiratory disease. ⋯ The median difference in the gradient was significantly higher in infants with PPHN (6.2 mmHg) compared to infants without PPHN (-3.2 mmHg, p = 0.022). The PaCO2-EtCO2 gradient was higher in infants with PPHN compared to term born infants without PPHN and decreased over the first week of life in infants with PPHN. The gradient might be utilised to monitor the evolution and resolution of PPHN.

Artificial intelligence model predicting postoperative pain using facial expressions: a pilot study.
This study aimed to assess whether an artificial intelligence model based on facial expressions can accurately predict significant postoperative pain. ⋯ ML models using facial expressions can accurately predict the presence of significant postoperative pain and have the potential to screen patients in need of rescue analgesia.

Autonomic dysfunction as a predictor of infection in neurocritical care unit: a prospective cohort study.
Infection in the neurocritical care unit ( NCCU) can cause significant mortality and morbidity. Autonomic nervous system plays an important role in defense against infection. Autonomic dysfunction causing inflammatory dysregulation can potentiate infection. We aimed to study the relationship between autonomic dysfunction and occurrence of infection in neurologically ill patients. ⋯ AD assessment can be used as a tool to predict development of infection in NCCU. This can help triage and institute early investigation and treatment.

Observational StudyGlucose measurements with accu check inform II versus hexokinase plasma method during surgery under general anesthesia, an observational cohort study.
Limited research exists on translation of in-vitro glucose measurement interfering compounds to the in-vivo situation. We investigated whether Point-of-Care glucose measurements by Accu Chek Inform II (ACI II) were accurate to monitor glucose concentrations during surgery with general anesthesia by comparing with the reference laboratory hexokinase plasma glucose test. ⋯ The agreement between glucose measurements using ACI II and the reference laboratory hexokinase test was clinically acceptable with a percentage error of 10.0% (95% CI 8.0 to 11.9). The use of TIVA may negatively affect the measurement performance of the ACI II.

LetterReevaluating optic nerve sheath diameter in predicting postdural puncture headache: exploring clinical implications beyond threshold values.
The study by Boyaci et al. assessed using optic nerve sheath diameter (ONSD) ultrasound to predict postdural puncture headache (PDPH) in spinal anesthesia patients. In their single-center study of 83 patients, PDPH incidence was high at 22.9%, partly due to the use of a traumatic needle. ⋯ ONSD's relationship with intracranial pressure (ICP) is acknowledged, but a definitive ONSD cutoff for PDPH is lacking. Other studies suggest ONSD changes may be linked to treatment outcomes in related conditions, emphasizing the importance of investigating risks of epidural blood patch failure.
