Effects of Closed Endotracheal Suctioning on Systemic and Cerebral Oxygenation and Hemodynamics in Children

Objectives: To evaluate the effects of closed endotracheal tube suctioning on systemic oxygen saturation, cerebral regional oxygen saturation, and somatic regional (renal) oxygen saturation and hemodynamic variables in children. Design: Prospective observational. Setting: A tertiary care PICU. Subjects: Children aged 0-18 years, requiring invasive mechanical ventilation and with an arterial line. Interventions: Closed endotracheal suction. Measurements and Main Results: The study included 19 sedated and intubated children, 0–18 years old. They were enrolled in an ongoing prospective observational study. We used near-infrared spectroscopy for cerebral regional oxygen saturation and somatic regional (renal) oxygen saturation. The timing of each closed endotracheal tube suctioning event was accurately identified from video recordings. We extracted systemic oxygen saturation, cerebral regional oxygen saturation, somatic regional (renal) oxygen saturation, heart rate, and systolic blood pressure and diastolic blood pressure for 5 minutes before and 5 minutes after each event and used these data for analysis. One-minute average values of these variables were used for repeated-measures analysis. We analyzed 287 endotracheal tube suctioning episodes in 19 children. Saline was instilled into the endotracheal tube during 61 episodes. The mean heart rate (107.0 ± 18.7 vs 110.2 ± 10.4; p

Written by Pendell Meyers, with edits by Steve SmithThanks to my attending Nic Thompson who superbly led this resuscitationWe received a call that a middle aged male in cardiac arrest was 5 minutes out. He was estimated to be in his 50s, with no known PMHx. He arrived with chest compressions ongoing, intubated, and being bagged. EMS report was that the patient had unknown down time with unwitnessed arrest, found initially in VFib arrest, defibrillated x1 followed by PEA arrest alternating with asystolic arrest during transport.He arrived in PEA arrest with a slow and wide cardiac waveform during initial rhythm check, with ...

I’ve had a case recently we’re my radial art line stopped working mid case. Attending thought I punctured at too steep an angle, but I’ve always used about 45 degree angle and then flattened. I generally use the arrow radial kits. Anyone have an idea about why arterial lines stop working, or am I actually going too steep?

Conclusion Results showed that the incidence of HEs after PSF in AIS can be as high as 31.3%. We did not find any significant risk factors. Although DNPD after PSF is a rare complication and we had none in this series, we suggest that these patients with multiple HEs may be at risk for DNPD as a result of hypotension and potential for cord ischemia. Therefore, all patients after PSF should be monitored in a pediatric intensive care unit–type environment or postanesthesia recovery room initially. If stable for, at least, the initial four hours, then patients should be good candidates for a less intensive environment. ...

CONCLUSIONS: CFTC performs well compared to stroke volume measurements on a Vigileo monitor. The use of CFTC is highlighted in resource-limited environments and when time limits the use of other methods. CFTc should be validated in a larger study with more operators against a variety of hemodynamic monitors. PMID: 29406045 [PubMed - in process]

AbstractThe aim of this study was to evaluate the accuracy and precision of non-invasive continuous blood pressure measurement by applanation tonometry (AT) in awake or anaesthetised cardiological intensive care patients. Patients suffering from highly impaired left ventricular function atrial fibrillation or severe aortic valve stenosis were included into the study. Arterial blood pressure was recorded by applanation tonometry (T-Line 400, Tensys Medical®, USA) and an arterial line in awake or anaesthetised patients. Discrepancies in mean (MAP), systolic (SAP), and diastolic (DAP) arterial pressure between the two met...

Editor —Arterial transducer infusion sets are associated with complications such as bacterial contamination and accidental arterial injection, potentially leading to bacteraemia, tissue necrosis and limb loss.1 In recognition of reported complications, the NHS England National Patient Safety Agency (NPSA)2 has issued warnings on the risks associated with accidental arterial injection, and the Joint Commission and the World Health Organization (WHO) have stated that injection ports on arterial catheters should be avoided.3 In England, after the 2008 National Awareness Alert, the NPSA required NHS hospitals to take imm...
