Family Presence During Electroconvulsive Therapy.

BACKGROUND: The practice of electroconvulsive therapy (ECT) is often hampered by stigma and myths prevailing among patients and families. Family attendance at ECT has not been systematically studied. METHODS: From January 2017 to May 2018, 69 consecutive patients were approached for family attendance at ECT. The inclusion criteria for entry to the ECT suite were consent from families and patients, age older than 18 years, and 1 family member at a time. After watching ECT, family members completed a multiple-choice questionnaire regarding their experience. RESULTS: Twenty-one family members watched ECT. A majority viewed the idea of attendance at ECT as reassuring, and a few indicated that it was anxiety provoking. Five participants (24%) felt distressed while watching the procedure, whereas 16 family members rated their experience as comfortable or rewarding (76%). In terms of the outcome, a clear majority have responded that watching the procedure alleviated their fears of ECT or provided transformative knowledge, whereas others felt no change in their attitude toward ECT (71% vs 29%). Most of the participants recommended watching ECT to other family members, whereas a minority was uncertain about their opinion (62% vs 38%). There were no adverse effects, premature exit from the ECT suite, interferences with treatment, or litigations. CONCLUSIONS: A clear majority of families viewed their attendance at ECT as a beneficial experience. Family presence during ECT may have the potential to promulgate its practice by reducing stigma and misconceptions.

An in vitro assessment of aerosol delivery through patient breathing circuits used with medical air or a helium-oxygen mixture.

BACKGROUND: The bench experiments presented herein were conducted in order to investigate the influence of carrier gas, either medical air or a helium-oxygen mixture (78% He, 22% O2), on the droplet size distribution and aerosol mass delivered from a vibrating mesh nebulizer through a patient breathing circuit. METHODS: Droplet size distributions at the exit of the nebulizer T-piece and at the patient end of the breathing circuit were determined by laser diffraction. Additional experiments were performed to determine the effects on measured size distributions of gas humidity and of the droplet residence time during transport from the nebulizer to the laser diffraction measurement volume. Aerosol deposition in the nebulizer, breathing circuit, and on expiratory and patient filters was determined by photometry following nebulization of sodium fluoride solutions into the breathing circuit during simulated patient breathing. RESULTS: With no humidification of the carrier gas, droplet volume median diameter (VMD) at the exit of the nebulizer T-piece was 5.5±0.1 µm for medical air, and 4.3±0.1 µm for helium-oxygen. Varying the aerosol residence time between the nebulizer and the measurement volume did not affect the measured size distributions; however, humidification of the carrier gases reduced differences in VMD at the nebulizer exit between medical air and helium-oxygen. At the patient end of the breathing circuit, droplet VMDs were 1.8±0.1 µm for medical air and 2.2±0.1 µm for helium-oxygen. The percentages of sodium fluoride recovered from the nebulizer, breathing circuit, patient filter, and expiratory filter were, respectively, 29.9±8.3, 40.4±5.6, 8.3±1.5, and 21.5±2.1% for air, and 32.6±2.2, 36.3±0.7, 12.0±1.4, and 19.1±1.1% for helium-oxygen. CONCLUSIONS: Ventilation with helium-oxygen in place of air-oxygen mixtures can influence both the droplet size distribution and mass of nebulized aerosol delivered through patient breathing circuits. Assessment of these effects on aerosol delivery is important when incorporating helium-oxygen into patient ventilation strategies.
