General Surgery Instruments Flashcards
What are two contraindications for Sengstaken-Blakemore tube?
- Esophageal strictures
- Recent esophageal or gastric surgery
What are complications of Sengstaken-Blakemore tube?
- Airway obstruction
- Esophageal rupture
- Aspiration pneumonitis
What is the indication of SB Tube?
In unstable patients with gastric/esophageal variceal hemorrhage when medical therapy with endoscopic hemostasis and vasoactive agents have failed
How to insert SB tube?
- Intubate patient
- Make sure SB tube has no air leaks
- Inflate gastric balloon
- X-ray patient to make sure gastric balloon is in the right place
- If bleeding doesn’t stop, inflate the esophagealballoon
- Don’t leave the esophageal balloon for more than 6 hours – risk of necrosis
- Admit patient to the ICU [Because there is risk of esophageal or gastric ruptures]
What are the indications of NG tube?
- Decompression of the stomach (stomach obstruction, stomach perforation, SBO)
- Monitoring upper GI hemorrhage
- Administration of medication and feedings to those unable to swallow
What are contraindications of NG tube?
- Facial fractures (midface)
- Basilar skull fractures
- Esophageal strictures
What are complications of NG tubes?
- Epistaxis
- Sinusitis
- Accidental injury to nearby organs (esophageal perforation, pulmonary injury)
What are signs of basal skull fracture?
- Raccoon eyes
- CSF rhinorrhea
- CSF otorrhea
- Battle sign
- Hematotympanum
- Bump
What are indications for Central Venous Catheter?
- Hemodynamic monitoring (central venous pressure monitoring)
- Emergency venous access if peripheral venous access couldn’t be obtained
- For transfusing certain medications that are caustic to peripheral veins (chemotherapy, TPN)
What are contraindications of Central Venous Catheter?
- Coagulopathies or anticoagulant medications
- Infection over the placement site
- Vascular injury near the insertion site
- Morbid obesity
What are complications of Central Venous Catheter?
- Accidental puncture of arteries, leading to bleeding or hematoma formation
- Injury to the lung, possibly leading to pneumothorax
- Infection and sepsis
How do you treat pneumothorax?
- Decompress the chest by placing a large bore catheter in 2nd intercostal space, in the midclavicular line
- Chest tube is placed in the 4th/5th intercostal space to prevent air accumulation in the pleura
What is an indication of PEG tube?
Administering feeds/meds to patients with swallowing disorders or those who can’t currently swallow (ICU, comatose patients)
What are contraindications to PEG tubes?
- Coagulopathies
- Abdominal wall infection at placement site
What are complications of PEG tubes?
- Local infection at the insertion site
- Pneumoperitoneum
- Accidental insertion into nearby organs like the colon
