Arm && Interventions

Group	Intervention	Description
Erector Spinae Plane Block	Erector Spinae Plane Block	Patients with chest pain or upper abdomen underwent Erector Spinae Plane Block guided by ultrasound, bupivacaine 0.5% 20 ml was administered in the interfascial plane between the transverse process of T5 and the erector muscles of the spine, 60 minutes after dermatomes distribution was evaluated with pinprick and cold.

Primary Outcome Measures

Name	Time	Method
Dermatomes with sensitive block	60 minutes	Number (average) of dermatomes with sensitive block with pinprick and cold achieved at 60 minutes after the Erector Spinae Plane (ESP) block with 20 ml of bupivacaine 0.5%. Also, observe the distribution pattern.

Secondary Outcome Measures

Name	Time	Method
weight	60 minutes	weight in kilograms and its correlation with the main result The variables were grouped in means (standard deviation) for continuous variables and frequencies (percentages) for categorical variables.
Adverse events	60 minutes and 24 hours	Frequency of adverse events (hypotension, pneumothorax, neurological deficit, bradycardia) after the Erector Spinae Plane (ESP) block.
Visual Analogue Scale (VAS)	60 minutes and 24 hours	Change From Baseline in Pain Scores on the Visual analogue scale (VAS) from 1 to 10 at 60 minutes and 24 hours after the ESP block.
Height	60 minutes	Height in meters and its correlation with the main result The variables were grouped in means (standard deviation) for continuous variables and frequencies (percentages) for categorical variables.
Success rate	60 minutes and 24 hours	Success rate (Blocking of at least 2 continuous dermatomes at the puncture site measured with pinprick and cold)
Degree of satisfaction	60 minutes and 24 hours	Degree of satisfaction evaluated with the Likert scale of 4 points (1 dissatisfied, 2 slightly dissatisfied, 3 slightly satisfied, 4 satisfied).
Age	60 minutes	Age in years and its correlation with the main result The variables were grouped in means (standard deviation) for continuous variables and frequencies (percentages) for categorical variables.
