B-blocker in TBI

-propranolol at SICU admission decreases mortality without bradycardia

-no difference in hypotensive episodes

-propranolol IV 1mg q6hr (from separate study) — 40mg BID

-length of stay is longer for Bblocker, may be due to survival

Timing of rib stabilization

-EAST conditionally recommends for flail chest

-Later= 3-7days to see if patient fails non-op tx

-early= 0-2 days based on clinical/radiographic features predicting failure--

Fail chest (>= 3 consecutive rib fractures with at least 2 fractures each), >= 3 severely fxr ribs (bicortical displacement), volume loss.

-early group has less prolonged mechanical ventilation, less pneumonia.

-other study reports contraindications as pulmonary contusion requiring mechanical ventilation, other injury requiring prolonged mechanical ventilation.

High Grade Renal Trauma

-Grade 3-5 is high grade

-60% nephrectomy rate for grade 5

-grade 5 nephrectomy rate has not dropped significantly over time

-penetrating injury has higher nephrectomy rate

Cribrari modification

-want < 35% overtriage, want < 5% undertriage

-Need for trauma intervention (NFTI) may be a better indicator of appropriate triage

-NFTI= PRBC in first 4 hrs, discharge from ed to OR in 90min, ED to IR, ICU stay > 3edays, placed on vent outside of procedural anesthesia.

-use NFTI to analize the level 1 overtriages and other undertriages.

Red book (resources for the optimal surgical care)

Stop The Bleed

-B-Con course

-texas is #1 in instructors and in classes.

-Blueprint from UPMC:

1) identify need (active shooter, mass casualty, MTA, industrial accidents, MVC)

2) expert consultation

3) find people who know people who can advance program further, can use high volume non-trauma centers. Include EMS/fire/police and educators/schools. Include active community groups

4) build team (steering commitee) from region. For subcommtties in education, law enforcement, and educations

5) fundraising: look at hospital outreach budget, hospital foundations, philanthropy

6) implementation: find passionate advocates (prior regional events, law enforecement, EMS liaison). Train-the-trainer is high yield. Advertise the effort, can use the media. Can use a county-by-county roll out using a hospital and EMS in each region. Can get police officer continuing education credit.

9-14-17

Sepsis and advanced age

-age is strong risk factor for adverse outcomes

-age >= 55 is advanced age

-aged have delayed immunorecovery, greater organ dysfunction, increased catabolism.

Emergency general surgery volume and hospital mortality

-7 procedures account for majority of inpatient mortality: colon rxcn, sb rsxn, choley, bleeding PUD, LOA, appy, laparotomy

-technical complications had no difference from low to high volume hospitals

-low volume had higher sepsis, pulmonary complications, in patient mortality

**Idea**

-look at mortality/hospital stay/narcotic usage with hip fxrs admitted prior to and after Emcare start

REBOA versus Resuscitative Thoracotomy

-overall, REBOA has 6% complication versus RT 4% complication

-REBOA seems to be used more in blunt injury

-REBOA had increased survival out of ER and survival to discharge

-47% or REBOA need femoral cutdown

-REBOA outcomes improved when used prior to arrest.

Timing of venousthromboprophylaxis in severe pelvic fracture

-PE can be thromboembolic or primary pulmonary thrombosis

-pelvic fractures have high risk of bleeding and risk of DVT

-Early VTEp after TBI gives lower dvt and pe

-LMWH ma have improved survival over UH

-early VTEp is <=48hrs after admission

-early VTEp gives lower mortality in pelvic fxrs and less VTE

Interrupted versus continuous closures of abdomen in emergency laparotomy

-Annals of Surgery 1983 with 571 randomized pts had no difference; multiple other studies showed no difference

-most of the studies were elective surgeries

-European Hernia Society guidelines: small bite, continuous, absorbable suture is the way to go; but cannot comment on emergency surgery

-Tolstrup showed decreased dehiscence with interrupted in emergency surgery

-Technique: 0 non-looped PDS, 1cm from edge and between stitches—why did the study use 1x1cm bites when 0.5x0.5cm gives less hernia.

-interrupted is slower, no statistical difference in outcomes (limited by followup and sample size).

EGS mortality in high quality trauma center

-looking at relationship between trauma mortality and EGS mortality

-EGS has 8x mortality compared to elective

-looked at facilities with 200EGS cases and > 400 trauma admissions

-7 procedures caccounted for 8% of all cases, complications, deaths, and cost

-hospitals with lower TQIP trauma mortality also have lower EGS mortality

ICU management of Geriatric TBI

ICP monitoring= give advanced warning

-CPP may need to be higher in older (>60yo)

-studies show dec mortality and inc mortality or no change survival with ICP

-BEST TRIP study (ICP v clinical/CT monitoring)= no change in outcome with monitoring

-done outside US

-ICP monitor gave more ‘efficient’ care with less interventions to dec ICP

-ACS TQIP and guidelines for management of severe TBI recommend ICP but don’t tell us who to place it in.

-Brain org= age>40, SBP<90 should have ICP monitor

Prognostic Models for Geriatric TBI

GTOS= specifically for geriatric trauma

-predicts in-hospital mortality

-requires ISS or AIS, not TBI specific

-GTOS II predicts disposition

Impact= predicts 6mo mortality and adverse outcome

-TBI specific

-overestimation of geriatric mortality

CRASH

-country specific

-TBI specific

-small overestimation of mortality

Palliative Care

-early provision of palliative care inc quality and length of life for life limiting conditions

-should not apply TQIP recommendation for not discussing prognosis in 1st 72hrs for geriatric TBI

-avoid #s in giving prognosis

-fluid situation

-address “palliative care bundle” daily

-Answer to pt/family Q’s: “it would surprise me if …” Ex ‘pt went home’

Helicopter versus ground transport

-helecopter advantages include speed, advanced capabilities, transfusions, airway management, experience.

-increased survival for abnormal RR (<10 or > 29), GCS < 14, hemo/pneumothorax even if helicopter transport takes longer than ground.

BIG= brain injury guidelines, modification below is being studied to minimize consults and resources

BIG-MaC 1= gcs 13-15, no focal neuro exam, no intoxication, no anticoagulation, no skull fracture, <4mm sdh, no edh, <4mm iph, <3 sulci and <1mm sah, no ivh

BIG-MaC 2= gcs 13-15, no focal neuro exam, yes intoxication, no anticoagulation, nondisplaced skull fracture, 4-7.9mm sdh, no edh, 4-7.9mm iph, single hemisphere or 1-3mm sah, no ivh

BIG-MaC 2= gcs any, yes focal neuro exam, yes intoxication, yes anticoagulation, displaced skull fracture, >8mm sdh, yes edh, >8mm or multiple iph, bi hemisphere or >3mm sah, yes ivh

Tx based on BIG-MaC score:

1- No admission, 6hr ER observation, no repeat CT, no NSG consult,

2- Hospital admission to floor, 24hr q8h observation, no repeat head CT, no NSG consult, GCS 15 for discharge

3- Standard care

ICP monitoring

-67-55 yo may have increased mortality

-NTDB suggest < 45 yo have increased survival

-3rd brain trauma foundation guidelines state: ICP should be monitored in all salvageable patients with severe tbi (GCS 3-8) and abnormal CT scan

-4th edition state it only decreases in hospital and 2 wk mortality

Early Complications of Bariatric Surgery

Leaks

RYGB= from tension on anastomosis; w/in 7d of OR

Dx: tachycardia > 120 à or

-CT with 100cc contrast 60-80% sensitive

-flouro gastrgraffin then thin barium

-above tests look at GJ anastomosis only

Tx: stable can be drained (95% close w/in 1mo); TPN, NPO

-Unstable (HR >120) à OR

-wide drain

-repair leak if able (omental patch with interrupted sutures)

-Gtube in remnant stomach

-control sepsis

Sleve= more common, less blood supply, higher pressure; can be associated with twist/kink/stenosis; most @ angle of His

Dx: tachy > 120; flouro

Tx: drainage / repair for unstable

-endoscopic stenting early can help with decreasing king (w/in 1 week)

Stenosis

RYGB

Dx: inability to swallow, can’t pass EGD scope (<9mm)

Tx: IVF, thiamine, neurology exam

-goal 10-16mm anastomosis

-only increase 2-3mm at a time

Sleve= may be twist/kink/stricture

Dx: flouro & EGD may be negative

Tx: stricture à balloon or surgical myotomy

-Twist/Kink à conversion to RYGB or total gastrectomy

Bleeding

-EGD to dx and tx; could be GJ or JJ

Balloons are meant to come out after 6mo.

Late Complications of Bariatric Surgery

Band

-Obstruction= vomit, PO intolerance, severe GERD

Dx: PA AXR (Phi Angle= spine to band angle nl 45-58degrees, 10:00 to 2:00)

-slipped band= stomach slipped under band, phi angle > 60degrees, can result in ischemia

Tx: deflate balloon (remove all fluid with 25g needle to port (max 4-13cc fluid)

-band erosion= subtle pain, GERD, slow erosion, not emergent, can see infection;

Tx: deflate balloon and endoscopic removal

-emergent OR for unresolved pain, obstructive sx.

-lesser curve of stomach is safe zone to cut band

Sleve= late complications are rare

RYGB (common internal hernia, PUD/marginal ulcer, gallstone

-SBO= dilated gastric remnant needs OR, gtube

-no blind NG tube

-Start exploration @ terminal ileum to approach retrograde

-close defect

-Marginal Ulcer= usually at GJ; epigastric pain

-Risks are smoking, NSAID, pouch dilation

-Emergent OR indications similar to PUD

-do graham patch or modified patch

-tx ulcer with PPI, stop smoking, stop NSAID; can address ulcer surgically later

-Biliary disease options include PTCD, CBDE, transgastric ERCP (put hole in gastric remnant, secure with stitch to hold through abdominal wall, place scope through abdomen)

4/1/22 Rib Fracture Plating

Studies

• Bulger, 1996. Elderly rib fxr mortality mortality increases 19% per rib

• Voggenreiter, 1998. Flail chest with pulmonary contusion not helped by orif— pul contusion not helped by orif. Excluded tbi. Had vent requirement.

• Complications of rib fxr

  • 9yr 64% pain

  • 2mo 66% disability

• Tanaka. RCT. Fewer vent, trach, in quality of life

• Pieracci, 2015. IS values increase with orif.

• Becks, 2019. Orif give improved mortality, vent, trach.

• Cwisociety.org

  • >= 3 rib displaced 50%

  • Rib 3-10

  • Fix in 72hr

  • >= 2 Physiologic factors

• Prins, 2020. Rib fxr and TBI with orif had improved survival, PNA. No change in vent.

• Indication for OR

• Orif in >80yo

  • Improved mortality, pna, narcotic use

Timing and indications for SSRF

• When

  • <72hr

  • Decreased or time, los, pna, trach

  • What comes first: spine, +/- long bone.

• Indications

  • flail chest = clinical flail with paradoxical motion

  • radiographic flail with >/= 2 ribs with >/= 2 fxrs

  • chest wall deformity with > 30% volume loss

  • partial displacement >/= 3 levels

  • CWIS Guidelines

  • Use fracture map. Dieffenbaugher rib fxr mapping tool.

  • Physiology: PIC score

    • Consider for any PIC >4.

• Expanded indications

  • Consider if have reason to wash out chest

  • Post cpr

  • Displacement on follow up imaging

  • Failure of non op

Chest wall approaches

• 3d recon with/without scapula

• Measure ribs- cortical thickness

• Inframammary incision

  • High medial anteriolateral

• AnteroLateral incision

  • Serrated m is in the way (stabilizes shoulder)

  • Avoid Long thoracic n

    • Identify

    • Avoid high muscle splitting incision due to risk of injury (incise seratus anteriorly, 2-3cm posterior from anterior insertion)

    • 
      

• Longitudinal

  • Medial fxrs (posterior)

  • Ausculatory triangle (lat/trap)

  • Mobilize skin flaps

  • Muscle splitting outside of triangle.

  • Leave paraspinous muscles in place (they help fixation) - angle of ribs

    • Don’t fix medial to paraspinous

• For gaps >1cm recommend ortho consult for prosthetic due to risk of non union

• Posterior and anterior fxrs do 2 incisions.

• Identify fxrs

  • US

  • Make line between highest and lowest fxrs

• Plate should be flush to bone

• Aim plate to upper/middle of rib as thinnest portion is inferior

Rib fracture program

• Pieracci program

• Doben

• Long program

• Can use kinetic taping of rib

• Selective bronchoscopy versus routine

• Consider spot film in OR bc screws aren’t counted

• Billing

  • By number of ribs

  • Vats bundled in

  • On Q is separate

• Rib cryoablation

  • Only for rib 3-9

  • High gives Horner syndrome

  • Low gives an wall pseudo hernia

• Risks
