-Tracheal stenosis is the most common late airway complication of post intubation/trachestomy resulted in hemodynamic deterioration and impairment of respiratory system mechanics. Post-dural puncture headache (PDPH) is well known complication of introduction of spinal/epidural needle in subarachanoid space. In this article, we present a very rare case report of a patient 18 year old male, diagnosis tuberculous meningitis(TBM) get prolong mechanical ventilation and dural puncture had developed tracheal stenosis and post-dural puncture headache . We describe a patient with PDPH and tracheal stenosis which was initially misdiagnosed as simple headache and asthma after prolonged tracheal intubation. Surgery is lifesaving for patients with critical tracheal stenosis, but how to ensure effective gas exchange is crucial to the anesthetic management.

CASE HISTORY:-A 18 year-old male who presented with a 6-week history of headache and fever and a 8-hour history of inability to speak and alteration in level of consciousness. There was history of neck pain, occasional nausea /vomiting and no neck stiffness .He had no other remarkable past history of medical and surgical illness. Before presentation, he had been kept on various intravenous antibiotics in private hospitals, with no clinical improvement. Physical examination showed a young man in an altered level of consciousness with signs of meningeal irritation and had left spastic hemiparesis. The patient had progressive respiratory distress with rapid shallow breathing, while using all accessory muscles of respiration. He had a respiratory rate of 35 breaths min -1 , and a fluctuating arterial oxygen saturation of 70~80% with 10 L.min -1 of supplementary oxygen. The patient was ventilated with the synchronized intermittent mandatory ventilation with volume controlled mode selected. The ventilatory settings were as follows: FiO 2 0.40; respiratory rate 14 breaths/min; Tidal volume500ml; pressure support 12 cm H 2 O; positive end expiratory pressure (PEEP) 5 cm H 2 O.With above mentioned settings, the peak airway pressure (PIP) was 16 cm H 2 O, and the arterial blood gas parameters were satisfactory .A lumbar puncture was performed with 23 G spinal needle and produced opalescent cerebrospinal fluid (CSF) with CSF pressure of 14 cm of H20. The biochemical/microbiological features of CSF are :-Protein 80mg/dl; glucose 40mg/dl; WBC 75 /micro L, chiefly there was Lymphocyte (70%)and CSF acid fast and grams staining were negative . CSF culture was not sent .The computed tomography scan of brain showed obstructive hydrocephalus. These above mentioned feature was suggestive of tuberculous meningitis .He was placed immediate on antituberculous drugs and intravenous steroids and mannitol .He was successfully weaned off mechanical ventilatory support after 10 days. After first day of weaning patient experienced of headache and vertigo. Intensivist assumed that headache and vertigo is a part of TBM and symptoms will subside after few da...
