Randomized Controlled Trial Comparative Study
A double-blind randomized clinical trial evaluating the analgesic efficacy of ketorolac versus butorphanol for patients with suspected biliary colic in the emergency department.
Patients presenting to the emergency department (ED) with suspected biliary colic often require intravenous (IV) analgesia. The choice of IV analgesia typically includes opioids and ketorolac. Although ultrasound (US) is the initial diagnostic study in these patients, nondiagnostic scans and a high clinical suspicion may require the patient to undergo hepatobiliary scintigraphy (HIDA). Opioids such as morphine interfere with the HIDA scan and thus may limit its value as an analgesic in the ED for these patients. Analgesics that do not interfere with HIDA scanning include ketorolac and butorphanol, an opioid agonist-antagonist. This study evaluates the efficacy of IV ketorolac compared to butorphanol for the treatment of biliary colic pain in the ED. ⋯ Although limited by small sample size and convenience sample, this study demonstrates that both ketorolac and butorphanol provide pain relief in biliary colic. Both agents should be considered reasonable options in the ED treatment of biliary colic, especially in patients that may undergo HIDA.

Randomized Controlled Trial
Success of ultrasound-guided peripheral intravenous access with skin marking.
The most effective technique for ultrasound-guided peripheral intravenous access (USGPIVA) is unknown. In the traditional short-axis technique (locate, align, puncture [LAP]), the target vessel is aligned in short axis with the center of the transducer. The needle is then directed toward the target under real-time ultrasound (US) guidance. Locate, align, mark, puncture (LAMP) requires the extra step of marking the skin at two points over the path of the vein and proceeding with direct visualization as in LAP. The difference in success between these two techniques was compared among variably experienced emergency physician and emergency nurse operators. ⋯ LAMP did not improve success of USGPIVA in variably experienced operators. Experience was associated with higher rates of success for USGPIVA.
