Summary
The quadratus lumborum block (QL block) effectively reduces pain and opioid use in nephrectomy patients. This novel analgesic technique offers improved side-effect profiles compared to traditional methods like epidurals.
Area of Science:
- Regional Anesthesia
- Pain Management
- Surgical Analgesia
Background:
- The quadratus lumborum block (QL block) is a regional anesthesia technique involving local anesthetic injection near the quadratus lumborum muscle.
- It is utilized for various surgical procedures, including abdominal and orthopedic surgeries.
- Limited data exists on QL block efficacy specifically for laparoscopic nephrectomy patients.
Purpose of the Study:
- To review and synthesize existing data on the use of quadratus lumborum blocks for analgesia in patients undergoing nephrectomy.
- To assess the efficacy and performance of QL blocks in the context of laparoscopic nephrectomy.
Main Methods:
- A comprehensive literature search was conducted on Pubmed, Embase, and Web of Science up to May 31, 2020.
- Search terms included variations of 'nephrectomy' and 'quadratus lumborum block'.
- Relevant clinical trials were assessed for quality using the Jadad scale.
Main Results:
- Twenty-three articles were reviewed from an initial search yielding 30 publications.
- Patients receiving QL blocks for nephrectomies demonstrated decreased opioid consumption.
- Reported outcomes included lower pain scores and better side-effect profiles compared to other analgesia methods.
Conclusions:
- The quadratus lumborum block is a beneficial analgesic option for patients undergoing nephrectomy.
- QL block offers a promising alternative for post-nephrectomy pain management.
- Further research may solidify its role in laparoscopic nephrectomy analgesia.

Abdominal Regions and Quadrants
14.2K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Local Anesthetics: Clinical Application as Spinal Anesthesia
962
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
