Objective

Identify from the RéAC registry, out-of-hospital sudden cardiac arrest in Caen and it's suburbs, to study epidemiology and assess our medical practices.

Study design

Observational, prospective and monocentric study.

Patients and methods

From March 2012 to March 2013, we identified 151 patients. Demographic parameters, delays until treatment, drugs given and patient outcomes were analyzed from the RéAC data registry. Depending on the variable studied, the statistical analysis used Mann-Whitney or the Chi² tests.

Results

Twenty-two patients were excluded (no resuscitation attempt and patients who were transported to hospital with chest compressions only, in the absence of spontaneous circulation). One hundred and twenty-nine sudden cardiac arrests were analyzed: 107 (83%) with medical origin and 22 (17%) with traumatic origin. Direct witnesses were present for 94 (73%) of them. Basic life support actions were begun for 59 (46%) patients and a telephone advice was issued by the medical response team for 47 (36%) of them. After an advanced life support, 74 (57%) patients died on the spot. Of the 55 patients reaching the hospital alive, 39 (71%) died in the intensive care unit and 16 (29%) were discharged alive from hospital, of whom 14 (88%) with a favorable neurological outcome.

Conclusion

RéAC national registry has allowed us to analyze epidemiological data on out-of-hospital sudden cardiac arrests in our center. This register has also allowed us to highlight areas for improvement. They should be taken into account to improve our medical practices.

Objectives

Stroke is a well-described postoperative complication, after carotid and cardiac surgery. On the contrary, few studies are available concerning postoperative stroke in general non-cardiac non-carotid surgery. The high morbid-mortality of stroke justifies an extended analysis of recent literature.

Article type

Systematic review.

Data sources

Firstly, Medline and Ovid databases using combination of stroke, cardiac surgery, carotid surgery, general non-cardiac non-carotid surgery as keywords; secondly, national and European epidemiologic databases; thirdly, expert and French health agency recommendations; lastly, reference book chapters.

Results

In cardiac surgery, with an incidence varying from 1.2 to 10% according to procedure complexity, stroke occurs peroperatively in 50% of cases and during the first 48 postoperative hours for the others. The incidence of stroke after carotid surgery is 1 to 20% according to the technique used as well as operator skills. Postoperative stroke is a rare (0.15% as mean, extremes around 0.02 to 1%) complication in general surgery, it occurs generally after the 24–48th postoperative hours, exceptional peroperatively, and 40% of them occurring in the first postoperative week. It concerned mainly aged patient in high-risk surgeries (hip fracture, vascular surgery). Postoperative stroke was associated to an increase in perioperative mortality in comparison to non-postoperative stroke operated patients.

Conclusion

Postoperative stroke is a quality marker of the surgical teams’ skill and has specific onset time and induces an increase of postoperative mortality.

Objectives

During continuous renal replacement therapy (CRRT), circuit clotting increases nursing workload, cost of the therapy and blood loss. The aim of this study was to assess the impact of a program designed to improve CRRT stability on unexpected circuit clotting.

Study design

Retrospective and observational study.

Patients and methods

In January 2011, several changes have been adopted regarding CRRT management. Regional citrate anticoagulation, continuous hemodialysis using super high-flux membranes and a specific training for intensive care unit nurses were implemented. CRRT sessions before (year 2009 and 2010, “Before group”) and after (year 2011 and 2012, “After group”) were analyzed. The primary endpoint was the incidence of unexpected CRRT session end.

Results

During the study period, 401 sessions performed in 152 patients were analyzed. Sixty-three unexpected session's end (40%) occurred before and 43 (17%) after the implementation of the program (P < 0.0001). Median filter life time was 33 (13–48) hours before and 55 (27–67) hours after (P < 0.0001).

Conclusion

Our program designed to improve CRRT stability reduced filter losses by reducing unexpected circuit clotting.

Day surgery is often considered as a marker of the necessity of reorganizing the hospital to take care globally and so better meet the expectations of improvement of the management of patients. But the actual deployment of day surgery can also act as a real revelation of the stakes of conciliation between the regulations, which supervise professional practices and organization, and the functioning of hospitals. Between the regulations supervising hospitals and professional practices and the place of the recommendations, between the general legal framework of the medical activity and specific legal framework (decree of anesthesia of 1994) and the Evidence-Based Medicine, the pretext of the improvement of the patient flow in day surgery, recommended by several institutions (Sfar, ANAP, HAS), questions about the legal obligation of the passage of all the patients in the postanesthesia care unit (PACU). Seen under the angle of a legal action against a medical doctor, the study of the French jurisprudence reveals that every practitioner has to respect the recommendations and the Evidence-Based Medicine, and this in the standardized frame of the MD's activity and the respect for a very strict legal environment. The question of an obvious conciliation between all these measures arises today clearly. In the case of a potential conflict, the key of resolution, based only on legal standards (constitution, laws, decrees), is not enough for arbitrating. Applying that the only respect for the decree of anesthesia would be enough for exempting itself from any contentious risk does not satisfy more. There is a real difficulty defining the legal precise nature of the recommendations, so best practices as better organization, which are more and more frequently. Even if these recommendations originally had not their place in the hierarchy of the legal standards, they are brought in there today. There is a real brake in the deployment of the day surgery because the strict respect for the decree of 94 on the systematic passage in PACU can be paradoxical with a better quality of the care. Twenty years after the publication of the decree of anesthesia, it seems essential to ask at first if it's possible to fast-track discharge without any stay in the PACU and thus of the inevitable conciliation between all these measures. Secondly it's necessary of modifying this decree to impulse the deployment of the day surgery.

Anaesthetists often stand in the front line to manage postpartum neurological deficits, although epidural analgesia is rarely responsible for these complications. An epidural analgesia was performed to relieve pain during spontaneous labor in a 34-year-old parturient. An emergency C-section was subsequently required due to fetal heart rate abnormalities. Twelve hours after catheter removal, the parturient developed a severe right leg motor and sensory neurological deficit, predominant on L5 and S1 roots and diagnosed by a neurologist as a central nerve root injury. Lumbar MRI identified a non-compressive epidural bleeding in front of the L5 vertebral body. Epidural bleeding after labor epidural analgesia is a rare complication that may jeopardize the functional prognosis. It may be difficult in some cases to differentiate an upper plexus injury due to labor and delivery from a central epidural analgesia-related nerve root lesion. Fetal head compression at the pelvic brim may induce neurological deficits in several well-differentiated nervous territories, thus mimicking an anaesthetic-induced perimedullar radiculopathy.

In patients with neuromuscular diseases, the use of rocuronium in the general anesthesia rapid sequence induction provides safety intubation conditions, but induces a deep and prolonged neuromuscular blockade. We report dose reduction to 0.8 mg/kg for a 47-year-old female with Landouzy-Dejerine myopathy. Therefore, less dose of sugammadex was given to reverse the neuromuscular block.
