Background: Necrotizing enterocolitis (NEC) is the most common and fatal gastrointestinal disease encountered in the Neonatal Intensive Care Unit. Several case reports have shown an association between supraventricular tachycardia and necrotizing enterocolitis. This study aimed to determine the association between supraventricular tachycardia and necrotizing enterocolitis. Methods: This study was conducted from April 1st, 2016 to March 31st, 2022, at the Department of Pediatrics, Zhongnan Hospital of Wuhan University, Hubei, China. The records of 74 subjects with the diagnosis of necrotizing enterocolitis (NEC) were obtained from the hospital’s medical data records. Consequently, 74 gender, gestational age, and birth weight-matched controls (babies without NEC) were recruited as controls. Results: Of the 74 cases, 47.3% of the cases were males, and 52.7% were females. Regarding the birth weight and gestational age, 77% of the cases had low birth weight (LBW) and 86.5% were premature. In terms of Apgar score, 93.2% of NEC cases had an Apgar score of >7 at five minutes. The median values of white blood cells, platelets, and hemoglobin of cases were 10.90 (8.09, 13.80), 227 (169.75, 295.50), and 155.6 (130.53, 170.95), respectively. No Association between supraventricular tachycardia and necrotizing enterocolitis (P = 1.00). Conclusion: No association between necrotizing enterocolitis and supraventricular tachycardia was found. Further multicenter-based studies examining whether there is a potential relationship exists between supraventricular tachycardia and the development of necrotizing enterocolitis are required.

Background: It is unknown whether stapling the mesh affects recurrence rate, incidence of neuralgia, and port-site hernia. We chose to fix it to the exterior reducing port size, cost and pain, at the same comparing this with traditional mesh stapling. Methods: We conducted a prospective trial for laparoscopic TAPP inguinal hernia repair on 120 patients in which we fixed the mesh to the anterior abdominal wall using either two prolene threads that passed to the exterior and tied in place or traditional mesh stapling. Results: The operative time is ranged from 35 to 70 minutes for external fixation, 30 to 60 minutes for mesh stapling, and 4 to 51 months for follow-up, and no recurrence occurred in both groups during the procedure. Two cases with post TAPP pain in mesh stapling patients are discussed with reduction of the cost and port size in external fixation patients. Conclusion: It is not necessary to secure the mesh during laparoscopic TAPP inguinal hernia repair from the interior and it is fixed only to the exterior allowing a reduction in size of the ports and considerable reduction in cost with elimination of TAPP associated post operative pain.

Background: Cardiothoracic surgery is a common cause of acute respiratory failure and is associated with increased morbidity and mortality. We aimed to compare the outcomes of open heart surgery patients treated using oxygen delivery devices with patients who receive NIV as a first-line therapy for hypoxemic respiratory failure. Materials and Methods: 40 patients who developed acute hypoxemic respiratory failure after open heart surgery and admitted to cardiothoracic ICU 20 patients received NIV and 20 patient received oxygen by venture mask. For all patients the following measurements were performed before and after CPAP AND Venture use: CBC, blood urea, serum creatinine body temperature, chest X-ray, Arterial blood gases (arterial pH, sodium bicarbonate, pcO2, SpO2 and PaO2-to-FiO2 ratio). Results: Mean PO2 and SO2 have increased after using of both venture and Cpap, increase in both PCO2 and HCO3 levels after using Venturi mask, CPAP mask was superior to venturi mask in avoiding the need of intubation, decreasing The ICU stay median length and also median length of hospitalization, all were lower in CPAP group than venture group. Also the mortality rate was lower in CPAP group than the venturi group. Conclusion: Using CPAP mask in severe AHRF following open heart surgery can avoid intubation, decreases the levels of tachypnea and arterial hypoxemia, decreases ICU stay, the length of hospitalization and also decreases the mortality rate compared with patients receiving high-concentration oxygen therapy with venture mask.
