RESUMO
BACKGROUND: Every summer, several patients who suffer from vertebral fractures are hospitalized at the Sainte-Anne Military Hospital after going on a boat trip around the French Riviera. The uniqueness of these fractures lies in their mechanism of injury, called the "deck-slap" injury. The aim of this study is to describe the characteristics of the "deck-slap" injury. METHODS: The data of 26 vertebral fractures that occurred during boat trips between January 2010 and September 2017 were collected and analyzed. RESULTS: The mechanism of injury observed was similar for every patient. Patients sitting on the front of the boat, or bow, (77% of cases, n = 20); patients being on a rigid-inflatable boat (65% of cases, n = 17); and when the sea state was calm (62% of cases, n = 16). The patients were bounced up in the air because of a strong wave and landed in a sitting position. The affected population was young (mean age of 42.5 years) and women were the main victims (sex ratio of 0.3). The lesion topography was found near the thoracolumbar junction in each case. It was always a vertebral body compression. Twenty-three percent of them (n = 6) suffered from neurologic complications. CONCLUSION: This type of fractures, frequently encountered during the summer, has not previously been described in the literature, yet is a relevant cause of hospital admissions to the emergency departments of the south of France. A better knowledge of this mechanism would provide a more efficient approach to prevention measures that should be imposed to potential boat passengers.

PURPOSE: In dogs intoxicated with bupivacaine, clonidine is effective to treat conduction disturbances and dobutamine corrects myocardial depression. We report the case of a patient who experienced severe bupivacaine cardiotoxicity and who was treated successfully using these medications. CLINICAL FEATURES: In a patient with pre-existing heart failure a surgical procedure to fix a humeral fracture was necessary. Preoperatively, heart failure was controlled with transcutaneous nitroglycerin and iv deslanoside. A bupivacaine bolus was administered iv accidentally (a mixture of bupivacaine 75 mg, 15 micro g clonidine). The patient developed nodal rhythm with extreme bradycardia, severe shock and convulsions. Seizures were controlled with thiopentone/succinylcholine. Epinephrine iv boluses (0.1 mg x 3) restored blood pressure (BP) to 50/30 mmHg and heart rate (HR) to 60 (nodal rhythm). Following 75 micro g clonidine iv, BP rose to 90/70 and HR to 90 min. Cardiac rhythm reverted to sinus rhythm with first degree atrio-ventricular block. Echocardiography showed hyperkinesia and relative hypovolemia that was controlled with iv administration of terlipressin and glucagon. Subsequent dobutamine infusion stabilized hemodynamic conditions. It was decided to proceed with surgery using a midazolam/sufentanil based general anesthetic. In the intensive care unit, recovery, extubation and weaning from the dobutamine infusion were realized within 16 hr of the event. CONCLUSIONS: In this patient with preoperative heart failure, clonidine was effective to treat bupivacaine induced conduction disturbances. Epinephrine and dobutamine were effective to treat myocardial depression and terlipressin effectively controlled vasodilatation.
