Although phrenic nerve palsy has been described as the most frequent complication, the vast majority of patients recover quickly.
To investigate the potential impact of topiramate on muscle contraction, phrenic nerve-hemidiaphragm preparations were used as an NMJ model and the effects of topiramate and phenytoin (as a control) on the muscle twitch response to electrical stimulation were comparatively evaluated.
3 Development of pulmonary complications after cardiopulmonary bypass is multi-factorial; alteration in the function of chest muscles and wall due to median sternotomy, systemic inflammatory response syndrome initiated by establishing cardiopulmonary bypass, phrenic nerve damage caused by administration of cold saline in the pericardial cavity during cardiac arrest and alveolar edema caused by left ventricular distension and elevated pressure in the pulmonary vasculature are considered the main contributing factors for this lethal complication.
In our study, the extrahepatic arterial collaterals supplying the liver cysts were demonstrated in 48% of patients, mainly through the right inferior phrenic artery and internal thoracic artery.
In the present study, the variations in the origination of inferior phrenic artery were observed.
Phrenic nerve injury following cryoballoon PVI is the highest reported complication.
Amyotrophic neuralgia associated with bilateral phrenic paralysis treated with non-invasive mechanical ventilation.
These included right intercostobronchial (RICB, n = 3), right bronchial (RB, n = 3), left bronchial (LB, n = 14), common bronchial (CB, n = 11), right intercostal (RI, n = 2), left intercostal (LI, n = 1), right internal mammary artery (RIMA, n = 3), right cervicothoracic (n = 2), left cervico thoracic (n = 1) and right inferior phrenic (n = 2) arteries.
In our study more postoperative complications like wound infection, sub hepatic collection, sub phrenic collection, chest infection, wound dehiscence and pancreatitis were seen in few cases which is not different from reported in local and international literature.
His reasoning was scientifically based, greatly enhancing its veracity: we should breathe through our noses to increase stimulation of the phrenic nerve, which lies adjacent to the nasal passage, thereby encouraging the diaphragm to descend more deeply and with greater strength.
Due to the high rate of phrenic nerve paralysis with interscalene blockade, the decision was made to attempt bilateral supraclavicular brachial plexus block placement using ultrasound guidance.
