Nicotine patches in patients on mechanical ventilation for severe COVID-19: a randomized, double-blind, placebo-controlled, multicentre trial.

PURPOSE: Epidemiologic studies have documented lower rates of active smokers compared to former or non-smokers in symptomatic patients affected by coronavirus disease 2019 (COVID-19). We assessed the efficacy and safety of nicotine administered by a transdermal patch in critically ill patients with COVID-19 pneumonia. METHODS: In this multicentre, double-blind, placebo-controlled trial conducted in 18 intensive care units in France, we randomly assigned adult patients (non-smokers, non-vapers or who had quit smoking/vaping for at least 12 months) with proven COVID-19 pneumonia receiving invasive mechanical ventilation for up to 72 h to receive transdermal patches containing either nicotine at a daily dose of 14 mg or placebo until 48 h following successful weaning from mechanical ventilation or for a maximum of 30 days, followed by 3-week dose tapering by 3.5 mg per week. Randomization was stratified by centre, non- or former smoker status and Sequential Organ Function Assessment score (< or ≥ 7). The primary outcome was day-28 mortality. Main prespecified secondary outcomes included 60-day mortality, time to successful extubation, days alive and free from mechanical ventilation, renal replacement therapy, vasopressor support or organ failure at day 28. RESULTS: Between November 6th 2020, and April 2nd 2021, 220 patients were randomized from 18 active recruiting centers. After excluding 2 patients who withdrew consent, 218 patients (152 [70%] men) were included in the analysis: 106 patients to the nicotine group and 112 to the placebo group. Day-28 mortality did not differ between the two groups (30 [28%] of 106 patients in the nicotine group vs 31 [28%] of 112 patients in the placebo group; odds ratio 1.03 [95% confidence interval, CI 0.57-1.87]; p = 0.46). The median number of day-28 ventilator-free days was 0 (IQR 0-14) in the nicotine group and 0 (0-13) in the placebo group (with a difference estimate between the medians of 0 [95% CI -3-7]). Adverse events likely related to nicotine were rare (3%) and similar between the two groups. CONCLUSION: In patients having developed severe COVID-19 pneumonia requiring invasive mechanical ventilation, transdermal nicotine did not significantly reduce day-28 mortality. There is no indication to use nicotine in this situation.

Effect of a Musical Intervention During the Implantation of a Central Venous Catheter or a Dialysis Catheter in the Intensive Care Unit: A Prospective Randomized Pilot Study.

BACKGROUND: Listening to music may reduce anxiety during medical procedures. However, the magnitude of any effect may differ with respect to patient and procedure. We evaluated the effect of a musical intervention on patient anxiety during a central venous catheter or dialysis catheter implantation in an intensive care unit. METHODS: A prospective single-center controlled open-label 2-arm randomized trial was conducted in a medical intensive care unit (ICU) from February 2018 to February 2019. Patients undergoing central venous catheterization were randomized to listening to music or not during the procedure. Patients randomized to music listened to the Music Care application via headphones. The primary outcome was the change in anxiety assessed on a 100-mm Visual Analogue Scale between the beginning and end of the catheterization procedure. Secondary outcomes included postprocedural pain. RESULTS: We included 37 patients in the musical intervention group and 35 in the standard care group. The primary reasons for intensive care unit admission were the need for a central catheter for chemotherapy for hematologic malignancy and sepsis and/or septic shock in both groups. Postprocedural anxiety and pain assessments were missing in 1 (2.7%) and 4 (11.4%) patients in the intervention and standard care groups. We found no between-group difference in change in anxiety score: median -1 (interquartile range, -3 to 0) vs 0 (-3 to 0) in the musical intervention and standard care groups (median difference, -1 [-2 to 0]) (P = .24). Postprocedural pain score did not differ between the groups: median 0 (0-2) and 0 (0-3.75) in the musical intervention and standard care groups (median difference, -0 [0-0]) (P = .40). To account for missing outcome assessments, sensitivity analyses were performed using 2 extreme scenarios, one favoring the standard care group (scenario 1) and the other favoring the intervention group (scenario 2). In either scenario, change in anxiety score did not differ between the intervention and standard care groups: -1 (-3 to 0) vs 0 (-4 to 0) (P = .88) in scenario 1 and -1 (-3 to 0) vs 0 (-2.75 to 1) (P = .07) in scenario 2. CONCLUSIONS: In this first randomized pilot study of musical intervention for central venous catheterization in awake patients in the intensive care unit, the musical intervention did not reduce patients' anxiety as compared with usual care.
