Outcomes of deep hypothermic circulatory arrest in pediatric cardiac surgery: A single center experience

AbstractBackgroundDeep hypothermic circulatory arrest (DHCA) is a technique used in the repair of complex congenital cardiac lesions that require aortic arch or pulmonary vein repair. DHCA has been linked to adverse outcomes and neurologic complications. Selective cerebral perfusion (SCP) may be added to DHCA to prevent neurological complication. Air embolism and hyperperfusion injury may be encountered. The aim of this study was to evaluate the safety and efficacy of simple DHCA and to outline the early outcomes especially the neurological ones.MethodsTwenty nine patients underwent surgical repair of congenital cardiac lesion with DHCA at a single institution from January 2010 to November 2015. DHCA was conducted with a target esophageal temperature of 18° and placement of an ice pack on the head. No selective perfusion was done. Demographic, operative and postoperative data were reviewed. Mortality, any neurological complications including seizers, coma, and stroke were recorded.ResultsThe mean age was 20.6 ± 8.2 months (range: 9 days to 154 months). The majority were males (20, 69%). The mean weight was 5.57 ± 4.2 kg (range: 2.3–17.5 kg). DHCA time was 20.03 min (range 3–52 min). There were three (10.3%) deaths. Two deaths occurred after Norwood operation, and one after interrupted aortic arch repair. None of the deaths were related to neurological injury. None of the patients developed seizers, coma, abnormal movement or neurological deficits.ConclusionsSimple DHCA without SCP is a safe, expeditious and reliable method for brain protection during repair of complex cardiac lesions, with acceptable outcomes

Divorce and Severity of Coronary Artery Disease: A Multicenter Study

The association between marital status and coronary artery disease (CAD) is supported by numerous epidemiological studies. While divorce may have an adverse effect on cardiac outcomes, the relationship between divorce and severe CAD is unclear. We conducted a multicenter, observational study of consecutive patients undergoing coronary angiography during the period between April 1, 2013, and March 30, 2014. Of 1,068 patients, 124 (12%) were divorced. Divorce was more frequent among women (27%) compared to men (6%). Most divorced patients had been divorced only once (49%), but a subset had been divorced 2 (38%) or ≥3 (12%) times. After adjusting for baseline differences, there was no significant association between divorce and severe CAD in men. In women, there was a significant adjusted association between divorce and severe MVD (OR 2.31 [1.16, 4.59]) or LMD (OR 5.91 [2.19, 15.99]). The modification of the association between divorce and severe CAD by gender was statistically significant for severe LMD (Pinteraction 0.0008) and marginally significant for CAD (Pinteraction 0.05). Among women, there was a significant adjusted association between number of divorces and severe CAD (OR 2.4 [95% CI 1.2, 4.5]), MVD (OR 2.0 [95% CI 1.4, 3.0]), and LMD (OR 3.4 [95% CI 1.9, 5.9]). In conclusion, divorce, particularly multiple divorces, is associated with severe CAD, MVD, and LMD in women but not in men

Anesthesia for tracheostomy for huge maxillofacial tumor

Providing sedation for patients with compromised upper airway is challenging. A 19-year-old female patient with huge maxillofacial tumor invading the whole pharynx scheduled for elective tracheostomy under local anesthesia due to compromised airway. The patient had gastrostomy tube for feeding. Venous cannulation was totally refused by the patient after repeated trials for exhausted sclerosed veins. Pre-operative mixture of dexmedetomidine with ketamine was administered through the gastrostomy tube with eutectic mixture of local anesthetics cream application over the planned tracheostomy site. The patient was sedated with eye opening to command. Local infiltration followed by tracheostomy was performed without patient complaints or recall of operative events

Re-exploration for bleeding after cardiac surgery: revaluation of urgency and factors promoting low rate

Abstract Background Re-exploration of bleeding after cardiac surgery is associated with significant morbidity and mortality. Perioperative blood loss and rate of re-exploration are variable among centers and surgeons. Objective To present our experience of low rate of re-exploration based on adopting checklist for hemostasis and algorithm for management. Methods Retrospective analysis of medical records was conducted for 565 adult patients who underwent surgical treatment of congenital and acquired heart disease and were complicated by postoperative bleeding from Feb 2006 to May 2019. Demographics of patients, operative characteristics, perioperative risk factors, blood loss, requirements of blood transfusion, morbidity and mortality were recorded. Logistic regression was used to identify predictors of re-exploration and determinants of adverse outcome. Results Thirteen patients (1.14%) were reexplored for bleeding. An identifiable source of bleeding was found in 11 (84.6%) patients. Risk factors for re-exploration were high body mass index, high Euro SCORE, operative priority (urgent/emergent), elevated serum creatinine and low platelets count. Re-exploration was significantly associated with increased requirements of blood transfusion, adverse effects on cardiorespiratory state (low ejection fraction, increased s. lactate, and prolonged period of mechanical ventilation), longer intensive care unit stay, hospital stay, increased incidence of SWI, and higher mortality (15.4% versus 2.53% for non-reexplored patients). We managed 285 patients with severe or massive bleeding conservatively by hemostatic agents according to our protocol with no added risk of morbidity or mortality. Conclusion Low rate of re-exploration for bleeding can be achieved by strict preoperative preparation, intraoperative checklist for hemostasis implemented by senior surgeons and adopting an algorithm for management
