Insights

Transient femoral nerve palsy can occur after ilioinguinal-iliohypogastric nerve blocks. This study found a partial iliac compartment block with lower bupivacaine concentration and volume caused this complication.

Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Nerve Blocks

Background:

  • Percutaneous ilioinguinal-iliohypogastric nerve blocks are used for analgesia.
  • Transient femoral nerve palsy is a known complication.
  • Higher local anesthetic volumes and concentrations are suspected causes.

Observation:

  • A case of partial iliac compartment block was observed.
  • This involved the lateral cutaneous nerve of the thigh and the femoral nerve.
  • A lower concentration (0.25%) of bupivacaine was used.

Findings:

  • The block used the smallest indicated volume (0.25 ml.kg-1).
  • A double-shot technique was employed.
  • This resulted in transient femoral nerve palsy despite reduced anesthetic parameters.

Implications:

  • Lower anesthetic concentrations and volumes may not eliminate the risk of femoral nerve palsy.
  • Careful technique and anatomical awareness are crucial in ilioinguinal-iliohypogastric nerve blocks.
  • This case highlights potential risks even with modified anesthetic administration.

Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

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 quadrants...
Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...
Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

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...
