About

Compare the ability of the transversus abdominis plane block (TAPB) and rectus sheath block (RSB) to provide surgical anesthesia for overweight and obese patients undergoing umbilical hernia surgery.

Full description

The purpose of this research study is to compare the ability of the TAPB and RSB to provide anesthesia for overweight and obese patients undergoing abdominal wall surgery. At the present time, this procedure is performed under general anesthesia, which often poses increased risks for overweight and obese individuals. It is not known if these blocks could be used to avoid the use of general anesthesia.

Enrollment: 15 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients ≥ 18 years of age undergoing umbilical hernia repair

Exclusion criteria

• Patient refusal or inability to provide informed consent
• True allergy, not sensitivity, local anesthetics
• True allergy, not sensitivity, Propofol
