RESUMO
Sudden cardiac arrest (SCA) remains a major healthcare issue worldwide with gloomy outcomes due to poor perfusion of cardiopulmonary resuscitation (CPR), deemed unsuitable for hemostatic conditions, cardiotorsal anatomy, electrophysiology, and thoracic biomechanics. Alternatively, we propose a new management, implementing rational exploitation of the stagnant blood masses: manually with a novel technique of cardiac massage and mechanically with a circulatory flow restoration (CFR) device. Methods: Simulated chest compressions were performed through the 5th intercostal space in professional Lifeguards volunteers, placed in the left lateral decubitus position with raised legs and abdominal compression. Results: Bypassing the sternal barrier, refilling the heart, and then compressing the chest with a recoil-rebound maneuver (3R / CPR) can significantly promote return of spontaneous circulation (ROSC). The effectiveness of the CFR device versus CPR has previously been demonstrated in the literature. Conclusion: Unlike current CPR, the 3R/CPR adapts human morphology and provides adequate myocardial perfusion promoting ROSC safely, under all circumstances. Preclinical computational models can confirm the effectiveness of the technique.
RESUMO
Delayed diagnosis of undescended testes is a major problem. A retrospective review of 298 testes units was performed to assess the age at referral, age at operation, complications and final outcome. The mean age at referral was 57 months. Only 24% of cases were operated below 2 years. A similar pattern of delayed orchidopexy has been reported by many other centres. As orchidopexy is recommended soon after 6-7 months of age, there is an urgent need for increased awareness of undescended testes and its consequences at all levels of child health care.
