Inflammatory myofibroblastic tumor (IMT), also called pseudo-tumor, is a very rare condition and accounts for less than 1% of primary lung tumor. It is most common benign tumor of lung in children. This case is reported with the objective of highlighting the role of manual trans-tracheal high frequency positive pressure ventilation (HFPPV) in facilitating surgical resection with maintenance of adequate oxygenation and a little compromised ventilation. A9-year boy, weighing 21 kg, was diagnosed as a case of IMTof left main bronchus on biopsy and was successfully treated by surgical excision through left thoracotomy. HFPPV through improvised technique was used for ventilation and oxygenation during surgery. Total Intravenous anaesthesia with propofol infusion and increments of fentanyl was used during HFPPV. After the completion of the surgery, conventional positive pressure ventilation (PPV) was continued through the endotracheal tube (ETT) to check any bronchial stump leak. After the surgery, patient was weaned and extubated in the operating room. Hospital course remained uneventful and the patient was discharged after 6 days. HFPPV with manually improvised technique is applicable in carinal surgery for optimization of oxygenation, ventilation, and uninterrupted surgical resection.
炎性肌纤维母细胞瘤(IMT),也称为假瘤,是一种非常罕见的疾病,占原发性肺肿瘤的比例不到1%。它是儿童中最常见的肺部良性肿瘤。报道该病例的目的是强调手动经气管高频正压通气(HFPPV)在促进手术切除、维持充足氧合以及轻度通气受损方面的作用。一名9岁男孩,体重21千克,经活检诊断为左主支气管IMT,通过左胸开胸手术成功切除。手术期间采用简易技术进行HFPPV以进行通气和氧合。在HFPPV期间,采用丙泊酚输注和芬太尼增量的全静脉麻醉。手术完成后,通过气管内导管(ETT)继续进行常规正压通气(PPV)以检查支气管残端有无渗漏。手术后,患者在手术室脱机并拔管。住院过程顺利,患者于6天后出院。采用简易手动技术的HFPPV适用于隆突手术,以优化氧合、通气和不间断的手术切除。
