RESUMEN
BACKGROUND: Cardiac implantable electronic device (CIED) procedures can cause significant post-operative pain. Opioid use for post-operative pain is associated with risk of persistent use. The benefits of pectoral nerve blocks (PECs) have been established for other chest wall surgeries but adoption in electrophysiology has been limited. OBJECTIVES: To evaluate the efficacy of intraoperative ultrasound guided PECs performed at the time of CIED procedures by the implanting physician from within the device pocket. METHODS: Patients undergoing a pectoral CIED procedure at 7 centers from 2022-2023 were included. Patients underwent intraoperative PECs and subcutaneous local anesthetic vs subcutaneous local anesthetic only at the discretion of the operator. Patients were prospectively evaluated for post-operative pain. RESULTS: 610 patients (67±15 years old, 63% male) were enrolled and half (n=305) underwent PECs. Patients who underwent PECs were more likely to have a history of chronic pain (32 vs 11%, p<0.001). PECs was associated with lower pain scores in the 4 hours after the procedure (1.5±2.1 vs 4.5±2.5, p<0.001). Pain scores were not different after 24-hours (2.8±1.7 vs 3.1±2.2) and 2-weeks (0.9±1.4 vs 0.9±1.2). PECs patients were less likely to receive inpatient opioids (10 vs 48%, p<0.001) and to be discharged with an opioid prescription (15 vs 59%, p<0.001). In multivariable linear regression, PECs (p<0.001), age (p=0.002) and absence of chronic pain (p=0.009) were associated with lower acute post-operative pain. CONCLUSIONS: Intraoperative PECs can reduce post operative pain and opioid use. This procedure can be readily performed by the implanting physician from within the device pocket.
RESUMEN
AIMS: Atrial fibrillation (AF) and chronic kidney disease (CKD) often coexist and share an increased risk of thrombo-embolism (TE). CKD concomitantly predisposes towards a pro-haemorrhagic state. Our aim was to evaluate the prognostic value of CKD in patients undergoing percutaneous left atrial appendage occlusion (LAAO). METHODS AND RESULTS: A total of 2124 consecutive AF patients undergoing LAAO were categorized into CKD stage 1+2 (n = 1089), CKD stage 3 (n = 796), CKD stage 4 (n = 170), and CKD stage 5 (n = 69) based on the estimated glomerular filtration rate at baseline. The primary endpoint included cardiovascular (CV) mortality, TE, and major bleeding. The expected annual TE and major bleeding risks were estimated based on the CHA2DS2-VASc and HAS-BLED scores. A non-significant higher incidence of major peri-procedural adverse events (1.7 vs. 2.3 vs. 4.1 vs. 4.3) was observed with worsening CKD (P = 0.14). The mean follow-up period was 13 ± 7 months (2226 patient-years). In comparison to CKD stage 1+2 as a reference, the incidence of the primary endpoint was significantly higher in CKD stage 3 (log-rank P-value = 0.04), CKD stage 4 (log-rank P-value = 0.01), and CKD stage 5 (log-rank P-value = 0.001). Left atrial appendage occlusion led to a TE risk reduction (RR) of 72, 66, 62, and 41% in each group. The relative RR of major bleeding was 58, 44, 51, and 52%, respectively. CONCLUSION: Patients with moderate-to-severe CKD had a higher incidence of the primary composite endpoint. The relative RR in the incidence of TE and major bleeding was consistent across CKD groups.

PURPOSE: Studies suggest that melatonin may prevent delirium, a condition of acute brain dysfunction occurring in 20%-30% of hospitalized older adults that is associated with increased morbidity and mortality. We examined the effect of melatonin on delirium prevention in hospitalized older adults while measuring sleep parameters as a possible underlying mechanism. METHODS: This was a randomized clinical trial measuring the impact of 3 mg of melatonin nightly on incident delirium and both objective and subjective sleep in inpatients age ≥65 years, admitted to internal medicine wards (non-intensive care units). Delirium incidence was measured by bedside nurses using the confusion assessment method. Objective sleep measurements (nighttime sleep duration, total sleep time per 24 hours, and sleep fragmentation as determined by average sleep bout length) were obtained via actigraphy. Subjective sleep quality was measured using the Richards Campbell Sleep Questionnaire. RESULTS: Delirium occurred in 22.2% (8/36) of subjects who received melatonin vs in 9.1% (3/33) who received placebo (Pâ¯=â¯.19). Melatonin did not significantly change objective or subjective sleep measurements. Nighttime sleep duration and total sleep time did not differ between subjects who became delirious vs those who did not, but delirious subjects had more sleep fragmentation (sleep bout length 7.0 ± 3.0 vs 9.5 ± 5.3 min; Pâ¯=â¯.03). CONCLUSIONS: Melatonin given as a nightly dose of 3 mg did not prevent delirium in non-intensive care unit hospitalized patients or improve subjective or objective sleep.
