RESUMO
Background: A diaphragmatic hernia is a defect or hole in the diaphragm through which abdominal contents can enter the chest cavity. Diaphragmatic hernias may be congenital (Morgagni hernia, Bochdalek hernia), a hiatal hernia, or acquired (iatrogenic and traumatic). Bochdalek's hernia typically occurs on the left side and rarely occurs in adults. Less than 100 cases of left Bochdalek's hernia in adults have been described in the literature. Most of them are asymptomatic. Case report: We report a complicated left Bochdalek hernia in a 43-year-old adult male who is a smoker. He came to the pulmonary clinic with symptoms and signs of pneumonia of the left lower lobe with persistent dyspeptic symptoms. Chest radiography revealed evidence of a left diaphragmatic hernia, which was confirmed by computed tomography of the chest and abdomen, and subsequently treated by left diaphragmatic repair via limited left thoracotomy. Conclusion: We report a rare case of a left Bochdalek hernia in an adult who underwent an appropriate left thoracotomy. Bochdalek hernias in adults are rare and usually asymptomatic, but when they become symptomatic, surgical intervention is required to avoid complications. BH should be considered in the differential diagnosis when radiographs suggest pneumothorax and should be treated early to avoid complications.
RESUMO
BACKGROUND: Increased lung water and the resultant atelectasis are significant pulmonary complications after cardiopulmonary bypass (CPB) in children undergoing cardiac surgery; these complications are observed after CPB than after anaesthesia alone. Ultrafiltration has been shown to decrease total body water and postoperative blood loss and improve the alveolar to arterial oxygen gradient and pulmonary compliance. This study investigated whether conventional ultrafiltration during CPB in paediatric heart surgeries influences post-bypass extravascular lung water (EVLW) assessed by lung ultrasound (LUS). METHODS: This randomized controlled study included 60 patients with congenital heart disease (ASA II-III), aged 1 to 48 months, with a body weight > 3 kg. Conventional ultrafiltration targeting a haematocrit (HCT) level of 28% was performed on the ultrafiltration group, while the control group did not receive ultrafiltration. LUS scores were recorded at baseline and at the end of surgery. The PaO2/FiO2 ratio (arterial oxygen tension divided by the fraction of inspired oxygen), urine output, and haemodynamic parameters were also recorded. RESULTS: LUS scores were comparable between the two groups both at baseline (p = 0.92) and at the end of surgery (p = 0.95); however, within the same group, the scores at the end of surgery significantly differed from their baseline values in both the ultrafiltration (p = 0.01) and non-ultrafiltration groups (p = 0.02). The baseline PaO2/FiO2 ratio was comparable between both groups. at the end of surgery, The PaO2/FiO2 ratio increased in the ultrafiltration group compared to that in the non-ultrafiltration group, albeit insignificant (p = 0.16). no correlation between the PaO2/FiO2 ratio and LUS score was found at baseline (r = - 0.21, p = 0.31). On the other hand, post-surgical measurements were negatively correlated (r = - 0.41, p = 0.045). CONCLUSION: Conventional ultrafiltration did not alter the EVLW when assessed by LUS and oxygenation state. Similarly, ultrafiltration did not affect the urea and creatinine levels, intensive care unit (ICU) stays, ventilation days, or mortality.
