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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Subjects were given informed consent before enrolling the study and randomized into two groups. Intravenous (IV) cannule with Ringer Lactate fluid, non-invasive blood pressure monitor, electrocardiogram (ECG) and pulse-oxymetry were set on the subjects in the operation room. Co-induction was done with midazolam 0,05 mg/kg and fentanyl 2 mcg/kg. Induction was done with propofol 1-2 mg/kg, followed by Laryngeal Mask insertion facilitated by atracurium 0,5 mg/kg. Maintenance was done with sevoflurane 1-2 vol%, O2:H2O = 1:2, flow 2 liter/minute. Surgery started. After final stitching, Group 1 received subconjunctival bupivacaine 0,5% 2,5ml in between stitches; Group 2 received subconjunctival NaCl 0,9% in between stitches. Both groups received paracetamol 20 mg/kgBW IV as post-operative analgesics. Hemodynamic, pain degree (using Visual Analog Scale / VAS), and nausea/vomiting incidence, and the time for first requested additional analgesia were recorded. Data was analyzed using SPSS (Statistical Package for Social Scientist), for numerical data using unpaired T-test or Mann-Whitney-U test, for categorical data using Chi-square test or Fischer Exact's Test. Data normality was tested by Kolmogorov-Smirnov test. Significant value is p<0.05.

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.

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
The degree of pain
Time Frame: 2 months
The degree of pain was measured in the morning after the surgery by Visual Analog Scale (VAS).
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The time for first requested post-operative additional analgesia
Time Frame: 2 months
The time for first requested post-operative additional analgesia was measured in minutes in the morning after the surgery
2 months
Side Effects
Time Frame: 2 months
post-operative nausea / vomiting incidence
