Impact of Radial Arterial Location on Catheter Lifetime in ICU Surgical Intensive Care.

The use of arterial catheters is frequent in intensive care for hemodynamic monitoring of patients and for blood sampling, but they are often removed because of dysfunction. The primary objective is to compare the prevalence of radial arterial catheter dysfunction according to location in relation to the radiocarpal joint in intensive care patients. DESIGN: Prospective randomized, controlled, single-center study. SETTING: The surgical ICU of the university hospital of Poitiers in France. PATIENTS: From January 2016 to April 2017, all patients over 18 years old admitted to the surgical ICU and requiring an arterial catheter were included. INTERVENTIONS: Randomization into two groups: catheter placed near the wrist (within 4 cm of the radiocarpal joint) and catheter placed away the wrist. The primary endpoint was the prevalence of dysfunction. We also compared the prevalence of infection and colonization. MEASUREMENTS AND MAIN RESULTS: One hundred seven catheters were analyzed (14 failed placements with no difference between the two groups, and 16 catheters excluded for missing data), with 58 catheters in near the wrist group and 49 in away the wrist group. We did not find any significant difference in the number of catheter dysfunctions between the two groups (p = 0.56). The prevalence density of catheter dysfunction was 30.5 of 1,000 catheter days for near the wrist group versus 26.7 of 1,000 catheter days for away the wrist group. However, we observed a significant difference in terms of catheter-related infection in favor of away the wrist group (p = 0.04). In addition, distal positioning of the catheter was judged easier by the physicians. CONCLUSIONS: The distal or proximal position of the arterial catheter in the radial position has no influence on the occurrence of dysfunction. However, there may be an association with the prevalence of infections.

Health related quality of life and predictive factors six months after intensive care unit discharge.

BACKGROUND: Advances in critical care medicine have improved patients' survival rate. However, physical and cognitive sequels after Intensive Care Unit (ICU) discharge remain substantial. Our objectives were to evaluate the Health-related Quality of Life (HRQL) at 6-month after ICU discharge and identify the risk factors of this outcomes. METHODS: We performed a single-centre prospective observational study. The components of Short Form 36 (SF-36) were analysed for assessing HRQL on preadmission and at 3- and 6-month after ICU discharge. RESULTS: During the study period, 438 patients were eligible for recruitment and 220 of them were included in the trial. During the follow-up period, bodily pain and role limitations relating to emotion were both improved in comparison to the preadmission status while physical role component was lower at 3- and 6- month after ICU discharge. There was no other significant change in the SF-36 domains. Mental as well as physical aggregates remained also unchanged. Most of preadmission SF-36 scores were lower in patients who died within the first 6 months of follow-up compared to those who are still alive. Factors independently associated with the 6-month HRQL were age, preadmission HRQL score, SAPS II, prolonged mechanical ventilation (>3 days) and the occurrence of acute respiratory distress syndrome. CONCLUSION: In our Cohort, ICU stay does not seem to alter globally neither the mental nor the physical component of the HRQL at 6-month after the discharge. However, some domains of the SF-36 are subject to significant changes.

Comparison of the McGrath® MAC video laryngoscope with direct Macintosh laryngoscopy for novice laryngoscopists in children without difficult intubation: A randomised controlled trial.

INTRODUCTION: Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The McGrath® MAC is a video laryngoscope with a curved blade similar to the Macintosh blade, which has not been previously described in first intention paediatric tracheal intubation. We aimed to compare direct laryngoscopy to the McGrath® MAC video laryngoscope among novice laryngoscopists. METHODS: Six paediatric anaesthesia residents with novice skills in paediatric laryngoscopy were randomly assigned to perform tracheal intubation using either direct Macintosh laryngoscopy (DL) or the McGrath® MAC video laryngoscope (MM) as the first attempted device in children weighing between 10 and 20kg without difficult intubation. RESULTS: Our study enrolled 132 children between August 2013 and April 2015. The time to intubation was shorter in the DL group (n=67) compared to the MM group (n=65) with 42s (35-50) versus 48s (43-58) P=0.002. The time to best view was similar between the two groups (10s [7-16] versus 10s [8-15]; P=0.50). The tube passage time was shorter with DL (29s [25-35] versus 35s [30-45]; P=0.0002) and either Cormak & Lehane grade or Percentage Of Glottis Opening (POGO) scores were similar between groups. Minor reversible respiratory adverse events were similar between groups: 12 in the DL group (17.9%) versus 12 in the MM group (18.5%). DISCUSSION: McGrath® MAC video laryngoscopy, when performed by a novice laryngoscopist on easy-to-intubate children, is associated with longer intubation times.
