Background/PurposeGastroparesis is a syndrome of delayed gastric emptying without obstruction. There are high rates of Emergency Department (ED) visits due to gastroparesis, and this chronic disease is difficult to treat which often leads to hospital admissions. This study aimed to evaluate the impact droperidol administration has on opioid therapy, symptom relief, co-administration of antiemetic and prokinetic medications, disposition, cost, and length of stay (LOS) of patients presenting to the ED.ResultsA total of 431 patients were identified and 233 met the inclusion criteria. Droperidol administration reduced the number of patients requiring opioid therapy (108/233 [46%] vs 139/233 [60%], P-value 0.0040), reduced patient-reported pain scales by 4 points, and reduced antiemetic therapy requirement (140/233 [60%] vs 169/233 [73%], P-value 0.0045). No differences were found in terms of ED LOS (Median 6 h [IQR 4-8] vs 5 h [IQR 4-9], P-value 0.3638), hospital LOS (Median 6 h [IQR 4-30 vs 7 h [IQR 4-40], P-value 0.8888), hospital admission rates (67/233 [29%] vs 71/233 [31%], P-value 0.6101), ED cost to the facility (Median $1462 [IQR $1114 - $1986] vs $1481 [IQR $1034 - $2235], P-value 0.0943), or hospital cost (Median $4412 [IQR $2359 - $9826] vs $4672 [IQR $2075 - $9911], P-value 0.3136).ConclusionIn patients with gastroparesis presenting to the ED, droperidol reduced opioid use, improved pain control, and decreased antiemetic use without any differences in MME per dose, length of stay, hospital admission rate, or cost.Copyright © 2023 Elsevier Inc.
