Anterior scalene plane block at the superior trunk level relieves referred shoulder pain after liver radiofrequency ablation: a technical report.

We report the first case of using an anterior scalene plane block at the superior trunk level achieving phrenic nerve blockade to treat intolerable referred shoulder pain after liver Radiofrequency Ablation (RFA) of a diaphragm-abutting liver tumor despite prevention with a full-dose non-steroidal anti-inflammatory drug. The anterior scalene plane block rapidly alleviated pain without significant complications.

Implementation of the acute care surgery model provides benefits in the surgical treatment of the acute appendicitis.

BACKGROUND: Several reports have indicated the benefits of the acute care surgery (ACS) model in surgical outcomes. We tried to delineate the impact of the ACS model on surgical efficiency and quality. METHODS: Before the ACS model was implemented, abdominal surgical emergencies were evaluated by an on-call nontrauma general surgeon (pre-ACS model). An in-house trauma surgeon treated all patients with trauma or nontrauma abdominal surgical emergencies after the ACS model. Patients with acute appendicitis who underwent appendectomies were included. We conducted a pre- and poststudy to compare the time patients were in the emergency department and surgical qualities. RESULTS: There were 146 and 159 patients enrolled in the pre-ACS model and ACS model, respectively. The overall ED length of stay in the ACS model was significantly shorter than that in the pre-ACS model (300.3 ± 61.7 vs 719.1 ± 339.0 minutes, P < .001). Hospital LOS was also significantly shorter in the ACS model than in the pre-ACS model (2.44 ± 1.39 vs 3.83 ± 2.21 days, P = .022). CONCLUSION: The ACS model may improve abdominal surgical efficiency and quality. Our study results echoed the benefits of the implementation of the ACS model shown in North America.

Selective computed tomography and angioembolization provide benefits in the management of patients with concomitant unstable hemodynamics and negative sonography results.

BACKGROUND: The FAST (focused assessment of sonography for trauma) examination can rapidly identify free fluid in the abdominal or thoracic cavity, which is indicative of hemorrhage requiring emergency surgery in multiple-trauma patients. In patients with negative FAST examination results, it is difficult to identify the site of the hemorrhage and to plan treatment accordingly. We attempted to delineate the role of selective computed tomography (CT) and transarterial angioembolization (TAE) in the management of such unstable patients. METHODS: From January 2005 to April 2011 patients with concomitant unstable hemodynamics and negative FAST examination results were identified. Their demographic and time to start of embolization were recorded. The initial systolic blood pressure (SBP) in emergency department patients was compared with the SBP after TAE. RESULTS: A total of 33 patients were enrolled, and 85% required TAE. SBP improved significantly after TAE. There were 18 patients who received TAE without CT scan because the site of hemorrhage was obvious. Fifteen patients received a CT scan during the time required for angiography preparation. Ten of them received subsequent TAE based on the CT scan findings, and the treatment plan was changed in the other five patients. There was no significant difference between patients with or without a CT scan with respect to the time interval between arrival and starting embolization. CONCLUSIONS: Transarterial angioembolization is suggested in the management of patients with concomitant unstable hemodynamics and negative FAST examination results. During the time interval required for angiography preparation, a CT scan can be performed. This approach provides valuable information for further decision making without delaying definitive treatment.
