Evaluation of an Intravenous Acetaminophen Protocol in the Emergency Department.

BACKGROUND: Acute pain is a leading reason for Emergency Department (ED) evaluation, accounting for nearly half of all ED visits. Therefore, providing effective non-opioid analgesics in the ED is critical. Oral acetaminophen (APAP) is commonly administered in the ED but is limited to patients tolerating oral intake. Intravenous (IV) APAP provides significant pain reduction parenterally. The purpose of this quality assessment project was to evaluate the frequency of opioid use in patients receiving IV APAP, the safety of IV APAP, and compliance with an ED IV APAP protocol. METHODS: This study included all patients who received IV APAP in the ED of a tertiary care, level I trauma center, during a three-month period. The protocol required ED patients to be NPO (nil per os), 18 years or older, and administered with a single 1000 mg dose. The adverse reactions within 24 hours post-IV APAP, ED length of stay (LOS), and opioid administration within four hours post-IV APAP were assessed. RESULTS: Ninety-four patients received IV APAP. All patients received a 1000 mg dose. One patient received more than one dose, but this patient had a 22-hour ED LOS. Two patients received oral medications within one hour of IV APAP (one received an antacid, and the other received carbamazepine and lamotrigine). An opioid was administered to 22 of the 94 (23.4%) patients during the four-hour protocol period. There were no reports of adverse reactions. CONCLUSIONS: The results show excellent compliance with the protocol. IV APAP was safe and well-tolerated. Notably, most patients did not receive an opioid within four hours of IV APAP. IV APAP can be safely and effectively utilized as an analgesic and lessen ED opioid use.

Perioperative Management of Patients on Maintenance Medication for Addiction Treatment: The Development of an Institutional Guideline.

With a brief summary of selected literature identified by a multidisciplinary panel of subject matter experts, the authors share their experience with the development of an institutional perioperative pain management guideline for patients on maintenance medication for addiction treatment (MAT), stressing the importance of perioperative continuation of opioid agonists such as methadone and partial agonists such as buprenorphine; and the discontinuation of opioid antagonists, such as naltrexone. The authors' protocol is appended as an example of a standardized approach to perioperative management of patients on MAT.

"Low-dose" recombinant activated factor VII results in less blood and blood product use in traumatic hemorrhage.

BACKGROUND: This study was designed to compare mortality and blood product use in patients who received recombinant activated factor VII (rFVIIa) for traumatic hemorrhage to a matched historic control. METHODS: Trauma registry data of bleeding trauma patients who received rFVIIa (40 microg/kg, repeated once if needed) included 28-day mortality; pre- and post-rFVIIa international normalized ratio; and packed red blood cell (PRBC), fresh frozen plasma, platelet, and cryoprecipitate requirements. A control group was created of bleeding patients who did not receive rFVIIa by matching for Injury Severity Score and age. The chi2 and Student's t tests were used to test for significance. RESULTS: Twenty-nine patients, well matched to 72 control patients, made up the rFVIIa group. rFVIIa corrected international normalized ratio within 4 hours (from 4.4 to 1.2; p < 0.0001). There was no difference in mortality (control, 40.3%; rFVIIa, 41.4%). The rFVIIa group required significantly fewer PRBC transfusions than the control group (18.3 +/- 7.5 vs. 22.0 +/- 9.7; p = 0.036). Compared with the control group, the rFVIIa group required fewer platelet transfusions (1.4 +/- 1.2 vs. 2.3 +/- 2.1; p = 0.01) and less cryoprecipitate (0.59 +/- 0.54 vs. 1.5 +/- 1.8; p = 0.006). CONCLUSION: rFVIIa resulted in significantly less PRBC, platelet, and cryoprecipitate use and equivalent mortality when compared with the matched control group, with no increase in complications.
