Purpose: Elbow dislocations are at risk for persistent instability and stiffness of the joint. Treatment with a hinged external fixation provides elbow joint stability, and allows early mobilization to prevent stiffness. Mounting a hinged elbow fixator correctly, however, is technically challenging. The low incidence rate of elbow dislocations with persistent instability suggests that centralization would result in higher surgeon exposure and consequently in less complications. This study aimed to investigate the results of treatment of elbow dislocations with a hinged elbow fixator on the rate of complications, range of motion, level of pain and restrictions in activities of daily living.

Methods: A retrospective observational cohort study in a level I trauma center, in which the majority of patients was treated by a dedicated elbow surgeon, was performed. All patients of 16 years or older treated with a hinged external elbow fixator between January 1, 2006 and December 31, 2017 were included. The fixator could be used (1) for the treatment of persistent instability in acute/residual simple and complex dislocations or (2) as revision surgery to treat joint incongruency or a stiff elbow. Patient and injury characteristics, details on treatment, complications, secondary interventions, and range of motion were extracted from the patients' medical files.

Results: The results of treatment of 34 patients were analyzed with a median follow-up of 13 months. The fixator was removed after a median period of 48 days. Fixator-related complications encountered were six pintract infections, one redisclocation, one joint incongruency, one muscle hernia, and one hardware failure. The median range of motion at the end of follow-up was 140° flexion, 15° constraint in extension, 90° pronation, and 80° supination.

Conclusion: A hinged elbow fixator applied by a dedicated elbow surgeon in cases of elbow instability after elbow dislocations can result in excellent joint function. Fixator-related complications are mostly mild and only temporary.

Efficiency and efficacy of planning and care on a post-anesthesia care unit: a retrospective cohort study.

BMC Health Serv Res 2020 Jun 22;20(1):566. Epub 2020 Jun 22.

Department of Anesthesiology, Erasmus MC, University Medical Center Rotterdam, P.O. Box 2040, 3000, CA, Rotterdam, the Netherlands.

Background: In the post-anesthesia care unit in our hospital, selected postoperative patients receive care from anesthesiologists and nursing staff if these patients require intensive hemodynamic monitoring or treatment to stabilize vital functions (e.g., vasopressor use and mechanical ventilation support) during a one-night admission. We investigated the agreement between elective preoperative planning for post-anesthesia care unit admission and the postoperative reality, along with the consequences of planning failures.

Methods: Data from records for 479 consecutive patients from June 1 to November 30, 2014, in a tertiary referral hospital were reviewed and analyzed. All patients admitted to PACU were included, along with patients scheduled to be referred to PACU but ultimately transferred to another ward. The primary outcome was the efficiency of planning PACU admission for elective patients. Secondary outcomes included secondary admissions to PACU or the intensive care unit (ICU) and 30-day morbidity and mortality.

Results: Of the 479 included patients, 342 (71%) were admitted per preoperative planning. Five patients (1%) needed cardiopulmonary resuscitation, and six (1%) did not survive the follow-up period. Patients admitted to PACU because of a shortage of beds in the ICU had the highest readmission (20%) and mortality rates (20%) (P = 0.01).

Conclusions: Preoperative planning for PACU admission was off-target for 29%. However, efficient care always takes precedence over efficient planning. In particular, downgrading patients to PACU because of a shortage of beds in the ICU was associated with a mortality increase.
