Serratus Block

Serratus Block(Single Shot)
Date/Time: []
Indications:  Pain control, chest wall injury
Provider: Self
A time out was completed, verifying correct patient, procedure, site, positioning, and equipment. Signed consent in the chart.
Patient’s [L/R] chest area was surveyed with ultrasound to identify appropriate landmarks. Chlorhexidine was applied topically to the skin. Using a 25 gauge needle (aspirating during insertion), 2mL bupivicaine was injected just under the skin as local anesthetic. Using a [22]ga needle under ultrasound guidance with constant aspiration while advancing, 10mL of 0.5% bupivacane was injected just under the serratus anterior, in the fascia. Distinct blackening was noted pushing the serratus apart from the intercostal muscle. This blackening was noted to extend anteriorly and posteriorly in the same plane as well as in the adjacent rib spaces. The patient was counseled on signs/symptoms of LAST.
 
Estimated blood loss: <1mL

Charting Tips

  • This block is primarily used for lateral chest wall injuries(rib fractures, chest tubes) and will not anesthetize the anterior chest wall
  • The term “single shot” is used because in the ED a catheter is not typically placed for continuous local anesthetic infusion
