Use of Intrathecal Analgesia in Appendectomy

December 10, 2019 updated by: Mehtap Balcı, Nigde Omer Halisdemir University

Comparison of Bupivacaine-Fentanyl and Bupivacaine-Alfentanil Used Intrathecally in Laparoscopic Appendectomy Surgery

Acute appendicitis which is the most common cause of acute abdominal pain, is an acute inflammation of appendix vermiformis. Appendectomy operations can be performed as laparoscopic and open surgery. Addition of opioids to intrathecal local anesthetics to improve the quality of preoperative analgesia is an increasingly used method in recent years. The aim of this study is to compare bupivacaine-fentanyl and bupivacaine-alfentanil which are used intrathecally to create motor and sensory block. 50 volunteer patients who were diagnosed as appendicitis by laboratory tests and clinical diagnostic methods in general surgery clinic and classified as American Society of Anesthesiologists Classification I-II (ASA Class I-II) aged between 20-60 years scheduled for laparoscopic appendectomy operation, were included in this study. The patients were randomly assigned into two groups, Group I and Group II. Patients received spinal anesthesia with either 10 mg heavy bupivacaine (2 cc)+25 mcg fentanyl (0.5 cc) intrathecally (Group I, n=25) or 10 mg heavy bupivacaine (2 cc)+250 mcg alfentanil (0.5 cc) intrathecally (Group II, n=25).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 60 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Group I
25 mcg fentanyl intrathecally
Drug: 25 mcg fentanyl
Before operation each patient was informed about the use of patient controlled analgesia system and visual pain scale (VPS) for pain scoring. In operating room all patient was monitored using electrocardiography (ECG), noninvasive blood pressure. Before spinal anesthesia 10-15 ml/kg intravenous serum saline infusion was started. Group I received 10 mg hyperbaric bupivacaine (2 cc) and 25 mcg fentanyl (0.5 cc).
Other Names:
  • fentanyl
EXPERIMENTAL: Group II
250 mcg alfentanil intrathecally
Drug: 250 mcg alfentanil

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Patients diagnosis with appendicitis
Time Frame: With the completion of laparoscopic appendectomy operation, average 30 minutes to 1 hour
50 volunteer patients diagnosis with appendicitis by laboratory tests and clinical diagnosis methods in general surgery clinic, aged 20-60 years with American Society of Anesthesiologists Classification I-II (ASA I-II) without contraindication for spinal anesthesia, scheduled for laparoscopic appendectomy operation were included. The patients were randomly assigned into two group.
With the completion of laparoscopic appendectomy operation, average 30 minutes to 1 hour
