An interventional study of Ultrasound guidance in Lipomas, sponsored by Suez Canal University. Completed at 1 site in Egypt. Open to participants aged 18 Years to 60 Years. Per ClinicalTrials.gov, last updated 2017-10-19.

There is limited information on using the ultrasonography for block placement concerning lipoma excision. A new type of regional blockade, performed under ultrasound, can ensure proper block placement with accurate local anesthetics deposition. Investigators hypothesized that ultrasound guidance can reduce the number of needle passes to complete the block placement. Investigators will compare namely ultrasound guided regional blockade and traditional method regarding the number of needle passes to complete the block placement.
50 patients between the ages of 18 and 60 years with American Society of Anesthesiologists (ASA) physical status I-III, scheduled for superficial subcutaneous lipoma (sized from 5 to 7 cm) excision will be enrolled in prospective comparative randomized clinical study.
Patients will be randomized into two groups: U (n = 25), in whom regional blockade was performed using US-guidance; and C (n = 25), in whom regional block was performed using the traditional method. Patients will be randomly assigned on a one-to-one ratio. Randomization will be performed by means of a computer generated random-numbers table. Group allocation will be concealed in sealed opaque envelopes that will not opened until patient consent had been obtained.
All patients will be pre-medicated with oral diazepam (7.5 mg) 30 min before the procedure, and IV fentanyl (50 ug) will be administered 5 minutes before placement of the block. Before the procedure, an IV access and standard monitoring of electrocardiogram (ECG), noninvasive blood pressure (NIBP), and peripheral oxygen saturation (SPO2) will be established.
Primary outcome includes the number of needle attempts (number of skin punctures and needle redirections) needed to complete the block placement. It will be documented by an investigator blinded to the aim of the study. Patient demographics, duration of surgery, patient's ASA physical status and other study outcomes will be documented by independent investigators who were not involved in the block placement procedure and were blinded to the group assignment.

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

This will utilize the traditional method of performance of regional block
In this arm, regional block will be performed under the ultrasound guidance
Procedure: Ultrasound guidance
In the second arm, ultrasound will be used to guide the regional block
The number of needle attempts needed to complete the block placement. New attempt will be defined as needle reinsertions through separate skin puncture.
Time frame: 10 - 20 minutes
The block success rate
The block success rate is assessed according to the adequacy of surgical anesthesia and is defined as complete loss of sensation to pinprick within 20 min of anesthetic administration and if no supplementation (sedative or analgesic) is required during surgery.Partial block is defined as inadequate sensory blockade after 20 min of anesthetic administration. The supplementation (additional LA infiltration or IV analgesic; fentanyl) is required to complete the proposed surgery. Failed block is considered if general anesthesia is required to complete the proposed surgery.
Time frame: 20 minutes
The incidence of adverse events
Time frame: 8 hours postoperatively
Plan to share: Undecided
