15 y/o M with SBO

HPI

• 15 y/o M with diffuse abdominal pain x 6 months and SBO. Transferred from OSH.

• 20 lb weight loss x 6 months

• Plan for PICC and PN, with plan for lap-assisted abdominal exploration later in week

PMHx: - Intermittent, mid-abdomen- No previous [abdominal] surgery- +Post-prandial pain - No rectal bleeding, perianal sx or extra-GI s/sx

Labs:CBC: WBC 5.8, Hct 35.9, Plt 265, PBS wnlBMP: Na 130, K 4.2, Cl 91, Glu 72, BUN 14, Cr 0.6LFTs: Alb 3.5, Pre-albumin

Amylase/lipase wnlOSH FOBT +

Page 8: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

15 y/o M with SBO

• Urgency of Abdominal Exploration?

• DDx?

• Fluid repletion / electrolyte goals

• Are you worried about the FOBT +?

• Would you place an NG prior to anesthesia?

• What is refeeding syndrome?

Page 9: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

Anesthetic Plan?

• Pre-med: 2mg IV midazolam

• Airway: Natural airway, NC

• Induction: Propofol 120mg

• Analgesia: Fentanyl 50 mcg

Page 10: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

Post-Anesthesia

• Started PN

• To OR for lap-assisted SBR --? 4cm terminal ileum w/ stricture removed

– C/f IBD given transmural inflammation and fissuring, previous perforation site

• Transitioned to PO diet on POD5, discharge with f/u colonoscopy

Page 11: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

SBO: Management Pearls

• Non-operative management successful in 65-81% of cases w/o peritonitis

– Without the presence of free air, SBO is a medical diagnosis

• Electrolyte abnormalities:

– hypo Na, K, H/Cl volume contraction alkalosis

– Refeeding sx phosphate, glucose, thiamine depletion in response to carbs K, Mg depletion Cardiac arrhythmias, respiratory muscle strength during anesthesia emergence, etc.,

• DDx is vast, but why do we care?

– Infection SIRS low SVR state, preload goals

– Hernia r/o strangulated components

– Chronic + wt loss r/o oncogenesis

– Adhesion/previous surg Bleeding, longer duration, opioid-induced ileus

– IBD

• NG provides symptomatic relief, decreases need for intraoperative decompression

– Must weigh against current n/v and patient discomfort with NG placement

– No outcome differences between NG and NJ

Page 22: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

Aplastic Anemia: Management Pearls• Misnomer - Primary failure or immunologically mediated

suppression of multipotent myeloid stem cells– Anemia + thrombocytopenia + neutropenia

• Etiologies: Chemicals, Drugs, infections

• DDx– Fanconi’s Anemia - PNH / c-Mpll– Dyskeratosis Congenita - Shwachman Diamond syndrome

• Electrolyte / Nutritional abnormalities (due to medications)– Hypo Na: SIADH, amphotericin-induced renal tubular

dysfunction– Hypo K: Amphotericin, furosemide (post-transfusion diuresis)– hypo Na, K, H/Cl volume contraction alkalosis

Page 23: Small Bowel Obstruction, Aplastic Anemia - Anesthetic Management

Aplastic Anemia: Management Pearls

• Antibiotic and other badness– Voriconazole visual disturbances (30%), transaminitis, QT

prolongation– Amphotericin – fevers (NLMS-like), renal/hepatic toxicity

• Infection precautions– Sterile technique with IV placement, Airway management (ETT or

LMA)– Apheresis platelets (single donor), leukocyte-reduced/irradiated pRBCs

• Transfusion thresholds / precautions– Institutional: Hgb < 6, Plt < 50; reassess in brisk bleeding scenarios– Non-infectious transfusion complications (TACO/TRALI, Fe overload,

DHTR)
