Absorbable sutures

Are broken down by the body via enzymatic reactions or hydrolysis - clinical status affects absorption rate e.g. sepsis

Monocryl = monofilament - increased throws for stable knot (9)
Vicryl - polyfilament, less throws (3) but increased fraying and local inflammation

Are commonly used for deep tissues and tissues that heal rapidly; as a result, they may be used in small bowel anastomosis, suturing in the urinary or biliary tracts, or tying off small vessels near the skin

Infection
Early breakage/loosening
Suture hypersensitivity
Local tissue inflammation

The diameter of the airway should not exceed that of the patient’s little finger. **Indications:** * Used to bypass obstructions in the mouth, nose, nasopharynx or base of the tongue. * Are typically better tolerated (and less likely to trigger the gag reflex) in patients who are partly or fully conscious compared to oropharyngeal airways. Nasopharyngeal airways should not be used in patients who may have sustained a skull base fracture, due to the small but life-threatening risk of the NPA entering the cranial vault. **Complications** * Epistaxis * Nasal trauma and bleeding * Brain herniation in basal skull fractures * Detoriation requiring intubation

**Ryles NG Tool** This is a Ryles nasogastric tube which is primarily used for decompression (drip and suck) in bowel obstruction, but can also be used to insert drugs or contrast into the GI tract. After explaining what you are about to do to the patient, you will require a NG tube which has been in the fridge as it is stiffer, some lubricant, a bladder syringe, a drainage bag and pH dipstick. The correct position of the tube is checked by aspirating gastric contents and checking for acidity on pH dipstick, if this is unavailable then air can be inserted to the tube and the epigastrium auscultated for bubbling. Finally, an x-ray can be taken to identify the tube. Once the tube is in the correct position a bag is attached and it is taped to the patients face. **Indications** * Bowel obstruction (drip and suck) * Gastric suction * Diagnostic purposes - to measure stomach acid **Complications** * Nose and throat irritation * Sinusitus * Pneumothorax * GI Bleeding * Aspiration * Tube dislodgement * Tube blockage
