Overnight: • Retroperitoneal Bleed • Vascular Surgery Consult: • No emergent surgery, watch. • CV and hemoglobin remained stable: • Hgb from 11.0 to 13.2 with 2nd Unit PRBC. • PA= 40/22, PCWP 12/CVP:14/CO=3/CI= 2. • Neosynephrine/norepinephrine changed to dobutamine/dopamine. • Serial Cardiac Enzymes followed. • Started on Hydrocortisone
Day 2: • Pulmonary consult: • Asked to help with vent management, wean, and etiology of poor pulmonary status. • Ventilator changed to SIMV, 12/15 PEEP 5 TV as tolerated, and FIO2 to 0.4 • Improved cardiac dynamics: • With improvement of CO/CI to 4.6/2.7. CVP 14, PAP 42/20, Wedge 13, and SVR 1150. BP increased from 87/56 to 102/60, and dopa/dobutamine were weaned off. • Echo: • Inferior/ posterior and lateral wma EF 35-40%, RV hypokinesis trivial MR.
Hemodynamic Effects of Positive Pressure Ventilation • Decrease in cardiac output (CO) & systemic hypotension • Accentuated by PEEP & auto-PEEP • Hypotension more likely with associated hypovolemia • Even low levels of PEEP can be deleterious for CO if the mean intrathoracic pressure is high • PCWP artificially elevated with positive pressure ventilation Marino, The ICU Book. 1990.
Day3-4: • NGT placed, and patient started on tube feeds • Remained Stable, began Vent Weans: SIMV rate=12, TV 600, PS=15 PEEP =5 FIO2 =40% • Pressors completely weaned • She started to have diarrhea Tm 37.9 HR 100-110 BP 90-100/5-60 O2 sats = 92%, IMV 12 TV 600 PSV 15 PEEP 5 9.3 7.42/45/139/28/98.4% 15.4 121 28.2 145 | 109 | 14 2.4 |26 | 0.3 202
Day 5: • K+ replaced: • Etiology felt secondary to diarrhea, as well as effects of mineralocorticoid and furosemide. • Patient began to spike fevers to 39.6 C. Pan cultured, WBC to 8.4. • ID consult requested. • Central line changed, arterial line changed, foley replaced, CXR done, and nasal culture, ETT sputum culture, urine culture. • Hgb stable 11.4, and she was placed back on clopidogrel. • Weaning off vent still difficult: • 6 hours on PSV, 15/5, 40%, returned to SIMV.
Day 6: • ID Consult: • Blood Cultures Negative • Check urine legionella antigen • Sputum Culture – Pseudomonas aeruginosa • Nasal Aspiratory Culture – Staph. aureus
Day 6: • ID Consult: • Blood Cultures Negative • Check urine legionella antigen • Sputum Culture – Pseudomonas aeruginosa • Nasal Aspiratory Culture – Staph. aureus • Treatment : Recommended and started on levofloxacin, ceftazidime, vancomycin. • Double cover Pseudomonas • Staph. aureus potentially MRSA. • Hemodynamics- Continued to improve: BP 130/70, Started auto diuresis – minimal furosemide. CVP 11 PA 40/25 PCWP 10 CI =3.1
Day 7: Febrile and hypotensive • Tm = 40.5 Newly hypotensive 80’s/40’s • WBC climbed to 10.9. • Metronidazole was added for continued diarrhea and stool was recultured for C.difficile • Fluid resuscitation started to keep blood pressure up, 1-2 doses of albumin tried to help pressure, and spare the use of pressors. • CXR remained unchanged. • Patient continued on ventilator weans • (PS 18, PEEP 5, 40% FIO2, failed to get to PS 10)
Colloid versus Crystalloid • Rationale: Colloid provides rapid volume expansion with a decreased risk of pulmonary edema • Colloid therapy slows progression of tissue injury in sepsis1 • No evidence for either improved outcome or increased mortality in patients given albumin2 • No evidence from RCTs that resuscitation with colloids reduces the risk of death compared to crystalloids3 • Morisaki H, et al. Compared with crystalloid, colloid therapy slows progression of extrapulmonary tissue injury in septic sheep. Journal of Applied Physiology. 1994;77:1507-1518. • Wilkes MM, Navickis RJ.

Day 8-9: Remained Stable, but… • WBC climbed to 19.0. • No new cultures positive, because of ongoing fevers – patient cultured daily for all sites. • Tube feeds stopped, and diarrhea resolved. C.difficile negative X3. • TPN started. Evaluation for PEG and tracheostomy requested, as patient was difficult to wean.
Day 10-12: • Stable, hemodynamically, but continued to gain weight/ fluid • WBC continued to climb (19,000), Fevers continued (38.4 C). • Peg and trach deferred. • Continued slow ventilator wean. • Family discussions started on long term prognosis. • Niece was DPOA • Patient never wished to be on long term ventilator support.
Day 13: Events: • Candida Albicans : • Blood cultures, Swan Cx, Pulmonary Artery Cath Cx, Arterial line Cx. • Sputum cx: Positive with rare yeast and pseudohyphae. • Blood Pressure fell to 80’s/40’s and Dopamine restarted • Fever spikes to 39.6, and WBC still at 21.4. • Started on Fluconazole per ID recommendations • Family Discussion Continued, Niece wished to talk with patient’s sister and brother before making a decision.
Day 14: • Resolution of fevers, WBC began to come down • BP stable at 100/60’s • PSV 16 PEEP 5 FIO2 0.4 • Family Meeting : Niece and Sister discuss near hopeless situation with team, and recapitulate patient’s wishes - that she would not want to remain vent dependent this long. This level of support would be against her wishes. • Patient was extubated, and expired with her family surrounding her at 4:10 p.m. No post-mortem exam.
