Electroconvulsive Therapy Considerations for Transgendered Patients.

As the transgender patient population continues to grow, health care providers will need to become aware of elements unique to the transgender community in order to provide the highest quality of care. Neuromuscular blockade with succinylcholine is routinely administered to patients undergoing electroconvulsive therapy (ECT). Decreased amounts or activity of pseudocholinesterase in serum can lead to prolonged duration of muscle paralysis. Causes of reduced action by pseudocholinesterase include genetically abnormal enzymes, reduced hepatic production, pregnancy, and various drug interactions. Estrogen supplementation taken by transitioning patients may affect the duration of neuromuscular blockade.This is a case of a 32-year-old male-to-female transgender patient with prolonged apnea following ECT treatment for severe, refractory depression. Further investigation revealed the patient was on estrogen therapy as a part of her transition and laboratory testing demonstrated reduced serum pseudocholinesterase activity. Further laboratory testing demonstrated reduced serum pseudocholinesterase activity. Succinylcholine dosing was titrated to an appropriate level to avoid prolonged apnea in subsequent ECT treatments. Physicians and other health care providers are faced with a unique population in the transgender community and must be aware of distinctive circumstances when providing care to this group. Of specific interest, many transitioning and transitioned patients can be on chronic estrogen supplementation. Neuromuscular blockade in those patients require attention from the anesthesiology care team as estrogen compounds may decrease pseudocholinesterase levels and lead to prolonged muscle paralysis from succinylcholine.

Success of spinal and epidural labor analgesia: comparison of loss of resistance technique using air versus saline in combined spinal-epidural labor analgesia technique.

BACKGROUND: Comparison of air versus saline for loss of resistance technique (LORT) in combined spinal epidural labor analgesia (CSE) has not been evaluated, and neither has the relation between CSE characteristics (the presence/absence of initial spontaneous clear fluid return or upon aspiration) and spinal/epidural analgesia outcomes. The authors hypothesized that there is no difference in the spinal analgesia success or epidural catheter efficacy between using air versus saline LORT for CSE. METHODS: A total of 360 patients were randomized to air or saline LORT for CSE. Primary outcome was spinal analgesia success as defined by verbal pain score of no more than 3 at 15 min after spinal dose administration. Secondary outcomes were CSE characteristics, catheter replacement, and average hourly epidural drug consumption. RESULTS: Results from 345 patients were analyzed. Spinal analgesia success, epidural catheter replacement, and drug consumption were not different between using air or saline LORT and were also independent of the presence/absence of fluid return on aspiration if initial spontaneous fluid returned to the spinal needle. However, epidural catheters inserted in absence of initial fluid return had a significantly higher catheter replacement rate (28.6%) than the 4.1% among those with initial fluid return (P < 0.03). CONCLUSIONS: Spinal analgesia success rate and epidural efficacy are independent of whether air or saline is used for LORT during CSE. Practice of aspiration for fluid after observing initial fluid return may be unnecessary because this practice does not alter spinal/epidural analgesia outcomes. However, epidural catheters inserted with the absence of initial fluid returned to spinal needle may pose a high failure risk.
