Randomized Controlled TrialIntraarterial Papaverine For Relief of Catheter Induced Peripheral Arterial Vasospasm During Pediatric Cardiac Surgery: A Randomized Double-Blind Controlled Trial.
Maintaining the patency of peripheral arterial lines in pediatric patients during surgery can be challenging due to multiple factors, and catheter-related arterial vasospasm is a potentially modifiable cause. Papaverine, a potent vasodilator, improves arterial line patency when used as a continuous infusion in the pediatric intensive care setting, but this method is not convenient during surgery. ⋯ In pediatric patients, papaverine injection immediately after peripheral arterial catheter placement was associated with relief of vasospasm and improved initial arterial line patency. Further, papaverine can be used as a rescue to improve and maintain arterial line patency.

Novel Utilization of Strand-Specific Reverse Transcription Polymerase Chain Reaction in Perioperative Clinical Decision Making for SARS-CoV-2 Polymerase Chain Reaction Positive Patients.
In order to prevent in-hospital transmission and potential complications related to SARS-CoV-2 in the perioperative patient, most healthcare institutions require preoperative testing for SARS-CoV-2 prior to proceeding with elective surgery. The Centers for Disease Control and Prevention (CDC) recommends a time and symptom-based duration of isolation for the presumed infectious period. ⋯ We describe the novel perioperative use of a strand-specific assay to detect minus strand ribonucleic acid (RNA) in a clinical decision-making algorithm to determine optimal timing of elective surgery after a patient tests RT-PCR positive for SARS-CoV-2. This is the first description in the literature of an attempt to further stratify patients who repeatedly test positive for SARS-CoV-2 into infectious versus non-infectious for perioperative planning.

Consistency of remifentanil concentrations in propofol-remifentanil infusions. A laboratory-based study.
There is increasing interest in two-agent single-pump intravenous infusions for anesthesia and sedation in pediatric patients. Propofol-remifentanil is one such mixture. The poor miscibility of such admixtures when remifentanil is added in very high concentrations and when the admixtures are maintained in static conditions has been demonstrated; however, these physiochemical properties have not been examined in clinically relevant concentrations or settings. ⋯ The concentration of remifentanil was 5 mcg.ml-1 +/- 0.5 mcg.ml-1 and was consistent across 57 min of infusion, and two different pediatric weight profiles.

Observational StudyCorrelation between bispectral index and patient state index in children under sevoflurane anesthesia.
Because the unanticipated arousal or hemodynamic instability during anesthesia may adversely affect the physical and emotional welfare of children, adequate management of the anesthesia depth is required. We aimed to compare Bispectral Index (BIS) and Patient State Index (PSI) in children during sevoflurane anesthesia and evaluate PSI as depth of anesthesia monitor in children aged 6 months-12 years. ⋯ There was a fair correlation between BIS and PSI in children under sevoflurane anesthesia. The use of BIS and PSI as an indicator for anesthesia depth by sevoflurane is not reliable in pediatric patients.
