The design of the hub with an integrated slittable valve is made for ease of use, and lowers concerns for lead dislodgement
as the sheath is removed.
Intraoperative problems include accidental tube dislodgement
, difficult surgical dissection due to involvement of vascular and pre-tracheal structures.
Although we did not encounter any difficulty in TTJV placement in our patients, dislodgement
of the catheter tip with the resultant complication of misplaced air insufflation is described in the literature (5, 6).
Another common issue regarding catheter stability is the catheter dislodgement
due to the AV dissociation occurring after the elimination of AP conduction when RF ablation is being performed during ventricular pacing in some unstable locations (6).
The observed events were LV lead dislodgement
, phrenic nerve stimulation (PNS) (electrical stimulation of the nerve that facilitates breathing), and other LV lead failures such as elevated thresholds, loss of capture and lead fracture.
The use of T-tube is associated with complication like bile leak, dislodgement
and even breaking of the T-tube, duct stricture, cellulites around the T-tube, cholangitis and trauma to duct and subsequent biliary leak during tube removal and delayed healing of the CBD wound.
The antagonists for its use argue that (1) it is unsuitable for insertion, as it has a high failure rate and airway rescue is more difficult, and (2) it is unsuitable for maintenance of anaesthesia, as positive pressure ventilation is difficult and dislodgement
and regurgitation can occur.
Stimulating the endocardial surface eliminates a myriad of complications associated with CS leads: acute and chronic lead dislodgement
, CS dissection, acute and chronic phrenic nerve stimulation, and high pacing energy thresholds.
5) Maintaining airway patency after induction, difficulty in intubation, perioperative dislodgement
of tube and decision of extubation are the critical events in anesthesia management.
Compared to other oesophageal stethoscopes, when using an endotracheal tube there is no danger of dislodgement
of attachments such as a glove-finger (1) or puncture of the cuff used on other oesophageal stethoscopes.
A new, randomized, controlled, non-inferiority study involving 302 subjects, funded by BD (Becton, Dickinson and Company) and 3M, found that using the BD Nexiva[TM] Closed IV Catheter System with the specially designed 3M[TM] Tegaderm[TM] IV Securement Dressing, provides effective catheter stabilization at a lower component cost and with a similar rate of securement-related complications (catheter dislodgement
, poor adherence, infiltration and leakage) as a traditional IV catheter with an add-on securement device.
All these morphological features of LAA impart irregularity to the lumen and can provoke the formation of thrombus and its dislodgement
in the event, if there is any cause for stagnation (left atrial arrhythmia, mitral valve pathology, atrial fibrillation, transient ischemic attack).
