Surgical repair of inguinal hernias is performed to fix a defect in the abdominal wall that allows abdominal contents to protrude into the inguinal canal, and it is one of the most commonly performed surgeries worldwide. This procedure is most commonly performed laparoscopically, especially in patients with recurrent or bilateral hernias, but can be performed open as well.  
The anesthetic technique ranges from local to spinal to general anesthesia. For a patient with no existing comorbidities, the decision can be based on the complexity of the anatomy, expected duration, surgeon preference, and/or patient preference.

Inguinal hernia repair is performed to fix a defect in the abdominal wall that allows abdominal contents to protrude into the inguinal canal, and it is one of the most commonly performed surgeries worldwide. This procedure is commonly performed laparoscopically, especially in patients with recurrent or bilateral hernias, but can be performed open as well.[1]

The anesthetic technique ranges from local to spinal to general anesthesia. For a patient with no existing comorbidities, the decision can be based on the complexity of the anatomy, expected duration, surgeon preference, and/or patient preference. Studies have found no difference between spinal vs GA (with LMA) in early or late outcomes[2].

Preoperative management

Patient evaluation

Adult patients presenting for inguinal hernia repair are usually healthy and this procedure is typically performed in the outpatient setting. However, this surgery can be emergent in cases of hernia incarceration or strangulation, usually requiring an open procedure.

System Considerations
Neurologic
Cardiovascular If strangulated, hypotension and tachycardia possible
Respiratory
Gastrointestinal If strangulated, dehydration from fever and emesis possible
Hematologic If strangulated, leukocytosis/leukopenia possible
Renal
Endocrine
Labs Hb/Hct for healthy patients, otherwise as indicated from H&P

Operating room setup

Patient preparation and premedication

  • Midazolam
  • Tylenol 1g

Intraoperative management

Monitoring and access

  • Standard ASA monitors
  • 5-lead EKG
  • 1 peripheral IV
  • Consider:
    • Urinary catheter
    • OG tube

Induction and airway management

  • If general, ETT vs. LMA
    • ETT with RSI if urgency does not allow appropriate NPO

Positioning

  • Supine, arms tucked

Maintenance and surgical considerations

  • If laparoscopic, place OG/NG before surgical incision to decompress the stomach if indicated

Emergence

  • Avoid nitrous until after abdomen is de-insufflated
  • PONV prophylaxis

Postoperative management

Disposition

  • PACU/holding area for 1-2h followed by discharge home

Pain management

  • Oral analgesics
  • Non-opioid analgesics
    • Ketoralac (Toradol)
    • Acetaminophen (Tylenol)
  • IV narcotics for breakthrough pain

Potential complications

  • PONV
  • Urinary retention (consider straight catheterization of bladder prior to emergence)
  • If laparoscopic, hemorrhage or organ damage from trocar insertion
  • Subcutaneous emphysema from pneumoperitoneum

Procedure variants

Open Laparoscopic Local/MAC
Unique considerations Preferred for recurrent or bilateral hernias Appropriate in some elective cases, surgeon-dependent
Position Supine Supine, arms tucked Supine, arms out
Surgical time 1-2h 1-2h
EBL <50mL <50mL
Postoperative disposition PACU 1-2h in PACU > home PACU
Pain score 3-4
Potential complications
  • Recurrence of hernia
  • Orchalgia, neuralgia
  • Bowel obstruction
  • Bladder injury (rare)
