ABSTRACT
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.
ABSTRACT
Background: Pulmonary complications after thoracic surgery are common and are associated with prolonged hospital stay, higher costs, and increased mortality. This study aimed to evaluate the value of The Assess Respiratory risk in Surgical Patients in Catalonia (ARISCAT) risk index in predicting pulmonary complications after thoracic surgery. Methods: This retrospective study was conducted at Almoosa Specialist Hospital, Saudi Arabia, from August 2016 to August 2019 and included 108 patients who underwent thoracic surgery during the study period. Demographic data, ARISCAT risk index score, length of hospital stay, time of chest tube removal, postoperative complications, and time of discharge were recorded. Results: The study involved 108 patients who met the inclusion criteria. Their mean age was 42.5 ± 18.9 years, and most of them were men (67.6%). Comorbid diseases were present in 53.7%, including mainly type 2 diabetes mellitus and hypertension. FEV1% was measured in 58 patients, with a mean of 71.1 ± 7.3%. The mean ARISCAT score was 39.3 ± 12.4 and ranged from 24 to 76, with more than one-third (35.2%) having a high score grade. The most common surgical procedures were thoracotomy in 47.2%, video-assisted thoracoscopic surgery (VATS) in 28.7%, and mediastinoscopy in 17.6%. Postoperative pulmonary complications (PPCs) occurred in 22 patients (20.4%), mainly pneumonia and atelectasis (9.2%). PPCs occurred most frequently during thoracotomy (68.2%), followed by VATS (13.6%), and mediastinoscopy (9.1%). Multinomial logistic regression of significant risk factors showed that lower FEV1% (OR = 0.88 [0.79-0.98]; p=0.017), longer ICU length of stay (OR = 1.53 [1.04-2.25]; p=0.033), a higher ARISCAT score (OR = 1.22 [1.02-1.47]; p=0.040), and a high ARISCAT grade (OR = 2.77 [1.06-7.21]; p=0.037) were significant predictors of the occurrence of postoperative complications. Conclusion: ARISCAT scoring system, lower FEV1% score, and longer ICU stay were significant predictors of postoperative complications. In addition, thoracotomy was also found to be associated with PPCs.
ABSTRACT
Background: Acute kidney injury (AKI) poses a significant morbidity and mortality risk to critically ill COVID-19 patients. The aim of this study was to investigate the incidence, predictors, and outcomes of AKI in patients admitted to the intensive care unit (ICU) with critically ill COVID-19 pneumonia. Methods: A multicenter retrospective study in Saudi Arabia of adult patients aged at least 18 years diagnosed with COVID-19 pneumonia and admitted to the intensive care unit between May 2020 and May 2021 was conducted. The occurrence of AKI and associated risk factors, the need for continous renal replacement therapy (CRRT), and the outcome were reported. Results: The study included 340 patients admitted to the ICU with COVID-19. Their mean age was 66.7±13.4 years, ranging from 49 to 84 years, and most of them were men (63.8%). The most common concomitant diseases were hypertension (71.5%), diabetes (62.4%), IHD (37.6%), CKD (20%), heart failure (19.4%), and 81.2% suffered from ARDS. AKI occurred in 60.3% of patients, 38% were stage 1, 16.6% were stage 2, and 45.4% were stage 3. Approximately, 39% of patients required CRRT, out of which 76.2% were stage 3, which was significantly higher than the other stages (p<0.001). AKI patients suffered significantly from asthma and had lower levels of C-reactive protein (CRP), ferritin, lactate dehydrogenase (LDH), and blood urea nitrogen (BUN) and higher creatinine levels than patients without AKI (p<0.05 all). The overall mortality rate was 39.4%, and the mortality rate was significantly higher in patients with AKI than in patients without AKI (48.3% versus 25.9%; p<0.001). Conclusion: AKI is common in adults admitted to the ICU with COVID-19 and is associated with an increased risk of death. Early detection of AKI and appropriate treatment can positively impact COVID-19 outcome. CRRT is the preferred dialysis method in critically ill ICU patients with AKI.
ABSTRACT
Background: A coronavirus pandemic (COVID-19) is associated with catastrophic effects on the world with high morbidity and mortality. We aimed to evaluate the accuracy of physiological shock index (SIPF) (shock index and hypoxemia), CURB -65, acute physiology, and chronic health assessment II (APACHE II) as predictors of prognosis and in-hospital mortality in patients with COVID-19 pneumonia. Methods: In Saudi Arabia, a multicenter retrospective study was conducted on hospitalized adult patients confirmed to have COVID-19 pneumonia. Information needed to calculate SIPF, CURB-65, and APACHE II scores were obtained from medical records within 24 hours of admission. Results: The study included 1131 COVID-19 patients who met the inclusion criteria. They were divided into two groups: (A) the ICU group (n=340; 30.1%) and (B) the ward group (n=791; 69.9%). The most common concomitant diseases of patients at initial ICU admission were hypertension (71.5%) and diabetes (62.4%), and most of them were men (63.8%). The overall mortality was 18.7%, and the mortality rate was higher in the ICU group than in the ward group (39.4% vs 9.6%; p < 0.001). The SIPF score showed a significantly higher ability to predict both ICU admission and mortality in patients with COVID-19 pneumonia compared with APACHE II and CURB -65; (AUC 0.89 vs 0.87; p < 0.001) and (AUC 0.89 vs 0.84; p < 0.001) for ICU admission and (AUC 0.90 vs 0.65; p < 0.001) and (AUC 0.90 vs 0.80; p < 0.001) for mortality, respectively. Conclusion: The ability of the SIPF score to predict ICU admission and mortality in COVID-19 pneumonia is higher than that of APACHE II and CURB-65. The overall mortality was 18.7%, and the mortality rate was higher in the ICU group than in the ward group (39.4% vs 9.6%; p < 0.001).
