An 8-year-old girl was admitted to the Pediatric Intensive Care Unit for severe ketoacidosis due to suspected inborn error of metabolism. She had been intubated with 5.5 size cuffed Portex® endotracheal tube (ET) and was on controlled ventilation initially. With supportive care, she started to improve and was given sedation holiday on day 4 of admission to assess for weaning readiness. She did not need sedative infusion and remained awake and calm. A few hours later, there was a noticeable leak in the ventilator graphic. The ventilator circuit was checked and found intact. The pilot balloon, cuff inflation line remained intact and cuff pressure maintained at 20 cm H2O. Lip level marking of ET tube had not changed, and there was bilateral equal air entry. Careful examination revealed that audible gush was noted around oral cavity. We planned for reintubation, as the exact reason of leak could not be ascertained. Upon extubation, a hole could be identified in the ET that was presumably caused by trauma due to biting of the tube [Figure 1].

Common reasons for new-onset circuit leak include unrecognized disconnections in the ventilator circuit, partial or complete tracheal extubation, incompetent pilot valve/balloon, line assembly leak, or damage. Damage to the ET is a relatively infrequent problem faced. There are previous reports of loss of integrity of ETs in adult patients and in operation theaters, with routine ET tube as well as reinforced tubes, but reports in children are scarce.[1],[2] Oral airways and bite blocks are used occasionally when children are agitated and risk injuring oral cavity or ETs. However, there are instances of pilot balloon malfunction as well due to bite block.[3] The index child did not need bite block and remained calm and cooperative, so the damage to ET tube came as a surprise. This report reiterates the need to consider the possibility of ET damage in addition to the usual causes when faced with circuit leak alarm and inability to ventilate.
