Study Notes

Surgical Wound Classification

An appendectomy for acute, unruptured appendicitis is a Class 3 (contaminated) wound.

Fire Extinguisher Use

Use a Class ABC extinguisher for fires caused by ignited disposable paper drapes during laser procedures.

Postoperative Care for Pediatric Patients

In the immediate postoperative period, check fingers for temperature and color for complications after closed reduction of fractures.

Fluid and Electrolyte Management

For a patient with significant burns (60%), monitor for potential fluid and electrolyte imbalance during the intraoperative period.

Malignant Hyperthermia Response

In suspected malignant hyperthermia, immediately call for the MH cart and Dantrolene when tachycardia, tachypnea, and elevated end-tidal CO2 occur.

Preoperative Lab Concerns

A potassium level of 2.5 is critical and concerning for a patient undergoing TURP, signaling potential risk for complications.

Surgical Incisions

The left subcostal incision is most commonly used for splenectomy procedures.

Pediatric Patient Outcome Standards

Pediatric patients should maintain normothermia, fluid balance, and normal oxygenation, which are all key outcome standards.

Anesthetic Agents

Succinylcholine is not an inhalation anesthetic agent compared to Halothane, Enflurane, and Nitric oxide.

Airway Management Technique

Sellick's maneuver involves applying pressure to the cricoid cartilage to occlude the esophagus and prevent vomiting.

Lidocaine Dosage Limits

The maximum recommended total dosage of lidocaine for local anesthesia should not exceed 350mg.

Arm Positioning Safety

When positioning a patient's arm, avoid abduction greater than 90 degrees to prevent injury to the brachial plexus.

Lithotomy Positioning

Slowly lowering the legs from the lithotomy position to supine helps facilitate safe transition and prevent complications.
