- Brief Summary
Regional anesthesia is defined as the temporary removal of nerve conduction and pain in certain areas of the body with local anesthetic drugs without causing loss of consciousness. Spinal anesthesia can provide better analgesia and shorter recovery time in urological procedures resulted in shorter operating times, lower postoperative pain, lower analgesic requirements, and shorter length of stay (LOS) compared to the general anesthesia. Lidocaine is an attractive regional anesthesia drug for ambulatory surgery since it has a rapid onset and rapid recovery from motor and sensory block. However, when it is compared with other local anesthetic agents, the use of lidocaine in spinal anesthesia is associated with an increased risk of transient neurologic symptoms, thus impeding its application to outpatient spinal anesthesia. Lidocaine is more neurotoxic than other local anesthetic agents, especially when high concentrations are applied directly to nervous tissue. Another local anesthetic agent can be used is prilocaine. It has medium potency, rapid duration, and rapid onset of action. Compared with lidocaine, prilocaine has a lower incidence of neurological symptoms in spinal anesthesia for outpatient surgery, and suitable as an alternative to long-acting low-dose local anesthetics. Therefore, the investigators intend to observe the efficacy and safety of these two agents in adult patients who will undergo cystoscopy procedure using spinal anesthesia. In this study the investigators used high-sensitivity C-Reactive Protein (hs-CRP) and high-sensitive Troponin (hs-Troponin). CRP is a systemic inflammation marker associated with conditions such as pain. Troponin can represent patient's kidney function since its metabolism and excretion are affected by changes of estimated glomerular filtration rate (eGFR). Previous study also showed that the use of spinal anesthesia can reduce the incidence of acute kidney injury. Therefore, the investigators aim to carry out further examination of the following two markers regarding to spinal anesthesia using lidocaine and prilocaine.
- Detailed Description
The investigators will conduct a double-blind randomized controlled trial to compare hs-CRP and hs-Troponin levels between prilocaine 2% and hyperbaric lidocaine 5% in adult patients undergoing cystoscopy procedure with spinal anesthesia. This study was approved by the Health Research Ethics Committee (Institutional Review Board) of Dr. Moewardi General Hospital Surakarta. Before randomization, participants who are eligible based on inclusion and exclusion criteria will be given informed consent. If the patients agree, the patient will be included in this research. Ninety adult patients will be randomly divided into control group and treatment group. Control group (group L) will be given 1 mL hyperbaric lidocaine 5% (50 mg) and treatment group (group P) will be given 2.5 mL prilocaine 2% (50 mg) as spinal anesthesia. The investigators will measure hs-CRP serum levels and hs-Troponin serum levels as the primary outcome. Serum levels of hs-CRP dan hs-Troponin will be measured 4 hours postoperative.

Group Intervention Description Group P Prilocaine 2% Drug: prilocaine 2% Dosage : 50 mg prilocaine 2% (2.5 mL volume) Group L Hyperbaric Lidocaine 5% Drug: hyperbaric lidocaine 5% Dosage : 50 mg hyperbaric lidocaine 5% (1 mL volume)
- Primary Outcome Measures
Name Time Method hs-Troponin serum level 4 hours postoperative Serum hs-Troponin at 4 hours postoperative \[ Time Frame: 4 hours postoperative \] hs-Troponin serum concentration will be measured using Enzyme-Linked Fluorescent Assay (ELFA) method as indicator of kidney injury comparing lidocain 5% hyperbaric and prilocaine 2%
hs-CRP serum level 4 hours postoperative hs-CRP serum concentration will be measured using particle enhanced immunoturbidimetry method as indicator of inflammatory biomarker resulted from pain due to surgery.
- Secondary Outcome Measures
Name Time Method Full regression of sensory block Through Study Completion, an average of 1 day Full regression of sensory block, defined as the duration (in minutes) between intrathecal drug injection and appearance of first pain sensation reported by patients and will be confirmed by using Visual Analogue Scale. The Visual Analogue Scale (VAS) is a 10 cm or 100 mm line with anchor statements on the left scale 0 represents no pain and on the right scale 10 (or 100) represents an extreme pain. The patient is asked to mark their current pain level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no pain" anchor point.
The incidence of adverse effects of hypotension Through Study Completion, an average of 1 day Hypotension will be defined as a systolic blood pressure of \< 90 mmHg or a decrease in mean arterial pressure (MAP in mmHg) of more than 20% from baseline preoperative value. MAP is measured from formula \[(2xsystolic pressure in mmHg) + diastolic pressure in mmHg)\] / 3
Pain score after cystoscopy procedure Through Study Completion, an average of 1 day Pain score after cystoscopy procedure comparing administration of lidocaine 5% hyperbaric and prilocaine 2% using visual analogue scale (VAS) on a 100- mm VAS. The Visual Analogue Scale (VAS) is a 10 cm or 100 mm line with anchor statements on the left scale 0 represents no pain and on the right scale 10 (or 100) represents an extreme pain. The patient is asked to mark their current pain level on the line. The examiner scores the VAS by measuring the distance in either centimeters (0 to 10) or millimeters (0 to 100) from the "no pain" anchor point.
The incidence of adverse effects of bradycardia Through Study Completion, an average of 1 day Bradycardia will be defined as heart rate \< 50 beat/min
The incidence of adverse effects of nausea. Through Study Completion, an average of 1 day Nausea will be assessed using (Visual Analogue Scale) VAS score for PONV (Postoperative Nausea and Vomiting). The severity of nausea was divided into four groups based on the VAS scale: 0-1 (no nausea), 1-4 (mild), 4-7 (moderate) and 7-10 (severe).
Duration of PACU (Post-Anaesthesia Care Unit) stay Through Study Completion, an average of 1 day Duration of PACU stay in minutes based on Bromage scale. Patients will be discharged from PACU if Bromage Scale \<2. Bromage scale is most commonly used, although this represents only lumbosacral motor fibers and have grading scale as follow:
0 : free movement of legs and feet with 0% blockade
1. : just able to flex knees with free movement of feet with 33% (partial) blockade
2. : unable to flex knee, but with free movement of feet with 66% (almost complete) blockade
3. : unable to move legs or feet with 100% (complete) blockade
