Clinical Trial Summary

This study aims to measure diaphragmatic dysfunction with ultrasonography and nerve stimulation of the phrenicus nerve, in patients undergoing thoracic surgery for lung and esophageal cancer, and correlate measures of diaphramatic function to clinical postoperative endpoints.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in excursion of the diaphragm	Ultrasonographic measure with M-mode of Diaphragmatic Excursion on right hemidiaphragm	Prior to surgery to 14 days after surgery
Secondary	Ultrasonographic measure of the difference in Intrathoracic Area	Intrathoracic Area is measured at inspiration and expiration to calculate the difference in Intrathoracic Area during breathing	Prior to surgery to 14 days after surgery
Secondary	Change in Diaphragmatic Thickening Fraction	Ultrasonographic measurement	Prior to surgery to 14 days after surgery
Secondary	Change in Intercostal Muscle Thickening Fraction	Ultrasonographic measurement	Prior to surgery to 14 days after surgery
Secondary	Change in forced expired volume within the first second (FEV1)	Spirometry	Prior to surgery to 14 days after surgery
Secondary	Change in forced vital capacity (FEV)	Spirometry	Prior to surgery to 14 days after surgery
Secondary	Change in peak flow	Spirometry	Prior to surgery to 14 days after surgery
Secondary	Change in Electromyographic measure of Maximal Diaphragmatic Response after stimulating the phrenic nerve		Prior to surgery to 14 days after surgery
Secondary	Change in Electromyographic measure of Latency of Diaphragmatic Response after stimulating the phrenic nerve		Prior to surgery to 14 days after surgery
Secondary	Change in 6 Minutes Walk Test	Maximum Walking Distance within 6 minutes	Prior to surgery to 14 days after surgery
Secondary	Change in visual analogue scale score	Scoring system for subjective sensation of pain ranging from 0 to 10. Higher numbers signify higher pain sensations	Prior to surgery to 14 days after surgery
Secondary	Accumulated Opiod Use after Surgery	Morphine equivalents	Prior to surgery to 14 days after surgery
