简要总结
The objective of our study was to evaluate the incidence of hemidiaphragmatic paralysis after ultrasound-guided stellate ganglion block (US-SGB) by assessing diaphragmatic excursion and diaphragmatic thickening fraction using diaphragm ultrasound.
详细描述
A prospective, single-center observational study was designed with the aim of evaluating diaphragmatic excursion and diaphragmatic thickening fraction, measured by ultrasound before and 30 minutes after US-SGB performed with 10 mL of 0.25% levobupivacaíne.

结局指标
主要结局
Diaphragmatic excursion
时间窗: The diaphragmatic excursion, assessed by diaphragm ultrasound before and 30 minutes after US-SGB.
Excursion of the diaphragmatic dome was assessed by a pulmonologist experienced in diaphragm ultrasound assessment. Once the dome was identified, excursion was measured in M-mode as the distance, in centimeters, between the end-expiratory and end-inspiratory positions during a vital capacity manoeuvre.
Diaphragmatic thickening fraction
时间窗: The diaphragmatic thickening, assessed by diaphragm ultrasound before and 30 minutes after US-SGB.
The diaphragmatic thickening fraction was assessed by a pulmonologist experienced in diaphragm ultrasound assessment. Diaphragm thickness was measured, in centimeters, at end-inspiration and end-expiration during a vital capacity manoeuvre. Thickening fraction was calculated using the following formula and expressed as a percentaje: Thickening fraction = \[(thickness at end-inspiration - thickness at end-expiration) / thickness at end-expiration\] x 100.
次要结局
- Forced vital capacity (FVC)(Spirometric parameters measured at baseline and 1 hour after US-SGB.)
- Forced expiratory volume in 1 second (FEV1)(Spirometric parameters measured at baseline and 1 hour after US-SGB.)
- Tiffeneau index (FEV1/FVC ratio)(Spirometric parameters measured at baseline and 1 hour after US-SGB.)
- Peripheral oxygen saturation (SpO2)(Measured at baseline and 1 hour after US-SGB.)
