Efficacy of Ultrasound-Guided Erector Spinae Block for Postoperative Pain Management in Nephrectomy
Efficacy of Ultrasound-Guided Erector Spinae Plane Block in Postoperative Pain Management in Nephrectomy: A Randomized Controlled Trial
This clinical trial aims to evaluate the effectiveness of the ultrasound-guided erector spinae plane (ESP) block in managing postoperative pain for patients undergoing open nephrectomy (kidney removal surgery). The study will compare this new technique to traditional pain management methods, such as opioid medications, to assess whether the ESP block reduces pain and the need for opioids after surgery.
Patients will be randomly assigned to one of two groups:
Group C will receive conventional pain relief methods, including opioids. Group E will receive the ultrasound-guided ESP block in addition to general anesthesia.
The main goals are to determine:
How much pain relief each method provides, measured using a visual analog scale (VAS).
The total amount of opioids required during the first 24 hours post-surgery.
Additional measurements will include monitoring vital signs like heart rate, blood pressure, and oxygen levels.
This study will help find safer and more effective ways to manage pain after nephrectomy, reducing the reliance on opioids and improving patient recovery

Yksityiskohtainen kuvaus
This randomized controlled trial aims to assess the efficacy of ultrasound-guided erector spinae plane (ESP) block in managing postoperative pain in patients undergoing open nephrectomy. Nephrectomy, a common procedure for kidney removal, often results in severe postoperative pain, which can contribute to complications such as postoperative pulmonary complications (PPC) and delayed recovery. Traditional analgesic techniques, including systemic opioids and epidural analgesia, have various side effects such as nausea, vomiting, constipation, and respiratory depression. Additionally, opioids may lead to tolerance, especially in cancer patients. Erector spinae plane block (ESP) is a newer regional technique that has gained attention due to its potential to provide effective analgesia with minimal side effects.
This study will evaluate whether the ESP block can provide better pain control and reduce opioid consumption compared to conventional pain management techniques. The ESP block targets the erector spinae muscle and provides analgesia via fascial plane blocks, which is believed to be effective in controlling visceral and somatic pain, typically associated with nephrectomy.
The trial will involve 66 adult patients scheduled for open nephrectomy under general anesthesia. Patients will be randomly assigned to one of two groups:
Control Group (Group C): Patients will receive conventional analgesia, including opioids and standard local anesthetic techniques.
Intervention Group (Group E): Patients will receive general anesthesia combined with the ultrasound-guided ESP block, administered immediately before anesthesia induction.
The primary outcome of the trial is to measure the first postoperative opioid requirement, utilizing the Visual Analogue Scale (VAS) for pain assessment. Secondary outcomes include the total opioid consumption in the first 24 hours, the intensity of postoperative pain at various time points, and the hemodynamic responses (heart rate, blood pressure). Additionally, peak expiratory flow rate (PEFR) will be monitored to assess respiratory function as part of the recovery process.
By evaluating these outcomes, the study aims to provide insights into whether ESP block can serve as a safer, effective alternative to traditional analgesia, improving postoperative pain management and reducing the risks associated with opioid use. The results may guide clinical practice in nephrectomy pain management, offering a potential improvement in patient recovery times and satisfaction.

|
Kokeellinen: Intervention Group: Ultrasound-Guided Erector Spinae Plane Block
Patients in this group will receive general anesthesia in combination with the ultrasound-guided erector spinae plane (ESP) block, administered before the induction of anesthesia.
The block targets the erector spinae muscle fascial plane, aiming to reduce postoperative pain and opioid consumption.
|
The Ultrasound-Guided Erector Spinae Plane (ESP) Block is a regional anesthesia technique used to provide postoperative pain relief.
In this study, the intervention involves the administration of a local anesthetic (0.25% bupivacaine) into the fascial plane between the erector spinae muscle and the transverse process of the vertebra using ultrasound guidance.
The procedure is performed immediately before the induction of general anesthesia in patients undergoing open nephrectomy.
The goal of the ESP block is to reduce postoperative pain, minimize opioid consumption, and improve recovery outcomes while maintaining hemodynamic stability.
This intervention is compared to conventional pain management methods, which primarily rely on systemic opioids and other standard analgesics.

Aikaikkuna |
|---|---|---|
|
Total Opioid Consumption
Aikaikkuna: Total opioid consumption will be calculated and recorded in mg within the first 24 hours postoperatively.
|
Total opioid consumption will be tracked and recorded for each group during the first 24 hours post-surgery.
The total amount of opioids used (in milligrams) will serve as an indicator of pain control effectiveness.
A reduction in opioid consumption in the ESP block group, compared to the control group, would suggest that the ESP block is effective in reducing the need for opioids, thereby minimizing opioid-related side effects.
|
Total opioid consumption will be calculated and recorded in mg within the first 24 hours postoperatively.
|
|
Peak Expiratory Flow Rate (PEFR)
Aikaikkuna: PEFR values will be assessed preoperatively and at arrival to 1, 3, 6, and 24 hours postoperatively.
|
PEFR will be measured preoperatively and at multiple points postoperatively (1, 3, 6, and 24 hours) to assess respiratory function.
This is particularly important in nephrectomy patients, as effective pain management helps promote better respiratory outcomes and reduce the risk of atelectasis or other complications.
A higher PEFR value suggests better lung function and recovery.
|
PEFR values will be assessed preoperatively and at arrival to 1, 3, 6, and 24 hours postoperatively.
|
|
Heart Rate (HR) Monitoring
Aikaikkuna: Heart rate (HR) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
Heart rate (HR) will be monitored preoperatively and at regular intervals postoperatively (0, 1, 3, 6, 12, 24 hours).
This will help assess whether the ESP block maintains hemodynamic stability without causing significant fluctuations, such as tachycardia (increased heart rate), compared to conventional analgesia methods.
|
Heart rate (HR) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
|

Aikaikkuna: Systolic blood pressure (SBP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
Systolic blood pressure (SBP) will be recorded preoperatively and at regular intervals (0, 1, 3, 6, 12, and 24 hours) postoperatively.
The aim is to evaluate whether the ESP block offers better hemodynamic control by preventing significant blood pressure fluctuations compared to conventional analgesia methods.
|
Systolic blood pressure (SBP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
|
Diastolic Blood Pressure (DBP) Monitoring in mmHg
Aikaikkuna: Diastolic blood pressure (DBP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
Diastolic blood pressure (DBP) will be measured preoperatively and at regular intervals postoperatively (0, 1, 3, 6, 12, 24 hours).
Monitoring DBP helps assess the stability of the cardiovascular system and ensure that the ESP block does not lead to significant hypotension or other adverse effects on circulation.
|
Diastolic blood pressure (DBP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
|
Mean Arterial Pressure (MAP) Monitoring in mmHg
Aikaikkuna: Mean arterial pressure (MAP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
|
Mean arterial pressure (MAP) will be monitored preoperatively and at regular intervals postoperatively (0, 1, 3, 6, 12, 24 hours).
MAP is a key indicator of perfusion pressure, ensuring adequate blood flow to organs.
This outcome will evaluate whether the ESP block maintains stable MAP levels compared to conventional analgesic methods.
|
Mean arterial pressure (MAP) will be measured preoperatively and at 0, 1, 3, 6, 12, and 24 hours postoperatively.
