About this study

Official title: Comparison of Caudal Block and Saddle Block on Anorectal Surgery

Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. Various surgical and anesthetic techniques have been used to increase the level of analgesia in perioperative period and decrease the length of stay in the hospital. In this study, investigators investigate the effects of routinely applied anesthesia techniques during anorectal surgery, caudal block and saddle block, on patients' perioperative hemodynamic values, sensory and motor block levels, and postoperative pain scores.

Read the detailed description

Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. Various surgical and anesthetic techniques have been used to increase the level of patients perioperative analgesia and decrease the length of stay in the hospital.

Spinal Saddle block anesthesia applications are performed while the patient is in the sitting position. Local anesthetic is given into the intrathecal space and it is aimed to localize the applied agent around the hip and anorectal region with the effect of gravity. Thus, sufficient level of anesthesia required during perianal region surgery and stable patient hemodynamics is provided. Caudal block is widely used in both adults and pediatric patients for intraoperative anesthesia and chronic pain management. Sacral hyperattenuation is performed to reach the epidural space, a local anesthetic agent is given to the epidural space, it is accepted as an easy and safe method and therefore it is frequently used in anorectal surgeons.

In this study, investigators investigate the effects of routinely applied anesthesia techniques during anorectal surgery, caudal block and saddle block, on patients' perioperative hemodynamic values, sensory and motor block levels, and postoperative pain scores. Elective anorectal surgery planned 100 patients between the 18-60 ages. The risk of anesthesia in patients will be determined by ASA (American Society Of anesthesiologists), ASA1 or ASA 2 risk group will be included after informed consents are approved.

Patient electrocardiogram (ECG), peripheral oxygen saturation (SpO2), non-invasive blood pressure monitor will be performed in the operation room. Baseline hemodynamic-vital parameters of the patients will be recorded. Patients undergoing caudal and saddle blocks, will be compared as two randomized groups.

In the saddle block group hyperbaric bupivacaine at a dose of 7 mg will be given to the intrathecal space after a 25 G quincke spinal needle is inserted with ultrasonography guidance between L4-L5 vertebral disc and clear cerebrospinal fluid is seen. The patient will be placed in sitting position for 5 minutes.

For the caudal block, sacral horns are palpated and sacral hiatus and epidural area will be determined at S4-S5 level through ultrasonography. The 20 G adult caudal needle will then be placed to the caudal epidural space and 25 mL bupivacaine at a concentration of 0.5% will be applied in the prone Jack-Knife position with resistance loss. Sensory and motor block level, heart rate (HR), systolic arterial pressure (SAB), diastolic arterial pressure (DAB), mean arterial pressure (OAB) and SpO2 levels will be measured every 5 minutes until the end of the operation. Sensory block level will be evaluated with "pinprick" test. Motor block level will be evaluated by using Modified Bromage Scale (0 = no paralysis, thigh, leg and foot can be removed, 1 = unable to move the thigh, move the knee,2 = cannot move the knee, can move the ankle, 3 = cannot move the lower extremities at all) Once sensory block level is reached to the L3 level the surgical procedure will begin.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • caudal blockProcedure or surgery

    For the caudal block, sacral horns are palpated and sacral hiatus and epidural area will be determined at S4-S5 level through ulştrasonography. The 20 G adult caudal needle will then be placed to the caudal epidural space and 25 mL bupivacaine at a concentration of 0.5% will be applied in the prone Jack-Knife position with resistance loss.

  • saddle blockProcedure or surgery

    In the saddle block group hyperbaric bupivacaine at a dose of 7 mg will be given to the intrathecal space after a 25 G quincke spinal needle is inserted with ultrasonographyguidance between L4-L5 vertebral disc and clear cerebrospinal fluid is seen. The patient will be placed in sitting position for 5 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The goal is to create adequate anesthesia for the surgeon to be painless

    When anesthetic agent is administered, the formation of sensory block at level lumbar 3 vertabra will be considered as an adequate level of anesthesia

    Measured: Sufficient anesthesia is expected within 30 minutes after the anesthetic agent is applied

Secondary outcomes (1)
  1. The goal is to provide pain relief in the postoperative period

    Pain measurement will be done with a visual analogue scale for 24 hours from the end of the operation. Visual Analog Scale (VAS) is used to convert some numerically unmeasured values into numeric values. Two extremes of a 100 mm line are to be assessed on two extremes and the patient is asked to indicate on the line where his situation is appropriate by drawing a line or placing a point or pointing. For example, for pain; no pain on one tip = 0, very severe pain = 100 on the other tip, and the patient marks his / her current state on this line. According to this chart, values of 50 mm and above are adversely affecting patient comfort. Patients with visual analog scale values above 50 mm will be intervened by making analgesic drugs.

    Measured: Postoperative follow-up for analgesia is 24 hours.

Questions about this trial

What is this clinical trial studying?

A study testing caudal block and saddle block in people with Anorectal Disorder, run by Kocaeli Derince Education and Research Hospital at 2 sites in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The goal is to create adequate anesthesia for the surgeon to be painless (time frame: Sufficient anesthesia is expected within 30 minutes after the anesthetic agent is applied). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Dec 2018.
