“…Among the 41 patients, 37 patients were successfully extubated with DE>1 cm.Hence we concluded that DE>1 cm could be considered for extubation. In the study conducted by Sabri et al [12], excursions in normal breathing ranged from 0.9 to 3.6 cm, with a mean of 2 cm; the mean excursion for the right hemidiaphragm was 1.85 cm; These values were also similar to the values obtained in our study.…”

Background and objectivesAn intensivist's decision, when it comes to weaning off a patient from mechanical ventilation and extubation, is based on many criteria. Problems can be associated with both prolonged ventilation and early extubation. Therefore, for optimal functioning of the diaphragm, the primary inspiratory muscle, it is important to resume spontaneous ventilation after extubation irrespective of the cause of respiratory failure. Thus, diaphragmatic parameters can prove useful in predicting the rate of success of extubation. However, till date in our institute, extubation has been done using only the standard parameters; hence, in this study, diaphragmatic parameters obtained by ultrasonography-diaphragmatic thickening fraction (dTF) and diaphragmatic excursion (DE) have been studied to predict extubation outcome.The objectives of this study are to (1) measure the diaphragmatic thickening fraction (dTF) in % and diaphragmatic excursion (DE) in cm before and after the spontaneous breathing trial (SBT) and ( 2) compare dTF and DE with standard extubation parameters in order to predict extubation outcome. Materials and methodsThis is a prospective, double-blind, observational study. The number of patients involved was 41. After obtaining ethical committee clearance, informed consent was taken from the patients' attendants. In this study, we divided doctors into the treating team and the research team. The treating team comprised the primary doctors working in the intensive care unit (ICU), and they evaluated the patients' readiness for pressure support ventilation. The research team performed diaphragmatic ultrasonography on those patients who met the inclusion criteria. The treating team was blinded to the dTF and DE results obtained by the research team. Prior to extubation, all the patients had to satisfy the standard extubation criteria followed at R. L. Jalappa Hospital and Research Centre (RLJH), Kolar ResultsWe observed that 68.29 (%) of the patients with normal dTF and DE values and 21.95(%) with slightly lower dTF and DE values were extubated successfully, and 7.31 (%) with normal dTF and DE values were reintubated; 2.43 (%) were extubated onto non-invasive ventilation (NIV). ConclusionFrom our study, we have concluded that bedside ultrasonography of the diaphragm, that is the measurement of diaphragm for dTF and DE always compliments the standard criteria for extubation and can be used for weaning the patients from mechanical ventilation, as bedside ultrasonography is not only easy and convenient but also a reliable parameter in predicting the outcome of weaning, however, it cannot be used as a sole criteria.

“…Common clinical features of pulmonary tuberculosis include productive cough of more than 3 weeks, weight loss, hemoptysis, night sweats, and prolonged low-grade fever (5). The diagnostic imaging modalities useful in their assessment are abdominal/ chest ultrasound, plain chest radiograph, Computerized tomography, and Magnetic Resonant Imaging (6,7).…”

Background: The diaphragm is one of the most important muscles of respiration in the body separating the abdomen from the thorax. Abnormalities of the diaphragm could be congenital or acquired, morphological or functional while pulmonary infection e.g. pulmonary tuberculosis, is implicated in its etiology. Case presentation: A 63-year- old man with six weeks history of cough productive of yellowish sputum. Chest X-ray showed a uniform well-circumscribed opacity in the right lower lobe abutting on or in continuum with the right diaphragm consistent with a diaphragmatic hump. Sputum Gene Xpert was positive for Mycobacterium tuberculosis. Chest CT scan revealed bilateral lymph node enlargement with hyperdense lesions in the anterior basal segment of the right lower lobe and medial bronchopulmonary segments of the right middle lobe. He was treated for 6 months with first-line anti-tuberculosis drugs. Discussion: The incidence of the diaphragmatic hump on chest radiograph worldwide and among Nigerians is unknown. The association of diaphragmatic hump with chest infection has been well document. The association of diaphragmatic hump with pulmonary tuberculosis is uncommon. Conclusion: A high index of suspicion is needed to diagnose pulmonary tuberculosis with atypical clinical and radiological presentations. Such prompt diagnosis will aid the treatment of the disease.

Background We aim to assess the role of diaphragm ultrasonography in evaluating the outcome of surgical diaphragmatic plication in adults with symptomatic unilateral diaphragmatic eventration. Results Forty patients with symptomatic unilateral diaphragmatic eventration underwent surgical diaphragmatic plication between 2015 and 2020. The etiology was idiopathic in 34 (85%) cases, and 37 (92.5%) of them were suffering from dyspnea. Diaphragm ultrasonography showed no diaphragmatic movement on the affected side in 10 (25%) patients and a paradoxical movement in 30 (75%) patients. Surgical diaphragmatic plication was done successfully in all cases. Postoperative complications were reported in 3 (7.5%) cases, with no mortality. There was a highly significant improvement in dyspnea at 1 week and 6 months follow-up. CXR showed a highly significant decrease in the mean height of eventration at 1 week 3.7 ± 1.2 cm (P < 0.001), and 6 months 2.6 ± 0.9 cm (P < 0.001), compared to preoperative values (10.1 ± 2.8 cm). diaphragm ultrasonography showed normal motility of the plicated cupola in all cases, and there was a highly significant decrease in the mean height of eventration at 1 week (3.1 ± 1.1 cm, P < 0.001), and 6 months (2.3 ± 0.5 cm, P < 0.001) compared to preoperative values (10.3 ± 2.2 cm). There was a highly significant increase in the diaphragm thickness at 1 week (2.7 ± 0.3 mm, P < 0.001), and 6 months (2.9 ± 0.2 mm, P < 0.001), compared to the preoperative value. There was a highly significant improvement in the degree of excursion 1 week (25 ± 4.3 mm, P < 0.001), and 6 months (28 ± 5.2 mm, P < 0.001), compared to the preoperative value (15 ± 6.2 mm). No fluid collection or surroundings organ injuries were detected. The mean FVC and FEV1 showed a highly significant improvement at 1 week (66.7 ± 6%, 78.2 ± 9.8%), and 6 months (68.8 ± 5.7%, 80.4 ± 10.3%), compared to the preoperative value (58.8 ± 8% and 70.9 ± 10.3%). Conclusions Surgical diaphragmatic plication is an effective and safe procedure that can be performed to treat symptomatic adults with unilateral diaphragmatic eventration. Diaphragm ultrasonography can be used as a simple bedside test to evaluate unilateral diaphragmatic eventration cases and their postoperative follow-up.
