19 RESUSCITATION Historic Concept
“Get the patient in shape so that surgery will be tolerated” This is an URBAN LEGEND (Abandon this concept) Trauma

20 What is RESUSCITATION ? Historic Concept
Assure an airway Control Bleeding Raise the BP (? Towards normal or HIGHER) Trauma 20

21 OVER

22 Fluids How Much (1963-1995) 2 LARGE BORE IVs
3 liter LR (or NS) in ambulance 3 liter LR (or NS) in ER “If a little bit is good a lot is better” Massive transfusion protocols End Points vague Trauma

23 Historic Approach 20th Century Algorithm
Replace blood with crystalloid in 3:1 ratio No concern for impact on bleeding

24 Historic How Accomplished ?
RESUSCITATION ? Historic How Accomplished ? Position Dressings & tourniquets Medications (vasoactive) Fluids, LOTS of fluids Lots of Complications Trauma 24

25 Fast FORWARD to the PAST
Trauma 25

26 Examine the PATIENT Trauma 26

27 Recognize the patient in need of EMS or EC, or OR “Intervention”
…and who does NOT need it Trauma 27

28 Less than 4% of ALL trauma patients actually need or benefit from “Resuscitation” (Whatever that is)
REALLY Trauma 28

29 Problems

30 MEDICAL DISASTER RESPONSE
NEW Classification

31 More than 90% of ALL trauma patients need NO “Resuscitation”

32 Some foundations for “resuscitation”
Trauma 32

33 William Shakespeare Trauma

34 “ ..to stop his wounds, lest he do bleed to death.”
…..or not so new “ ..to stop his wounds, lest he do bleed to death.” Shakespeare, The Merchant of Venice, Act IV, Scene I 1597 Stop the Bleeding – Go to OR

35 Stop the Bleeding

36 Walter Cannon Trauma

37

38 Cannon – World War I "The injection of a fluid that will increase blood pressure has dangers in itself. Hemorrhage may not have occurred to a marked degree because the blood pressure has been too low to overcome the obstacle offered by a clot.“

39 Less Resuscitation is Best
WWI lessons Cannon – JAMA “It is wasteful of time, resources and people to give fluid prior to operative control of hemorrhage.”

40 WW II Office of the Surgeon General
Trauma

41 Office of the Surgeon General, U. S. Army
WWII lessons 2 reports “BP should not be elevated and fluid not given till operative control of bleeding” Do not pop the clot and loose precious blood

42 1954-1960 CPR External Cardiac Compression (Elan, Safar, Kouwenhoven)
Trauma

43 Fluid 3:1 Rule DALLAS Original studies Shires, 1963
Described three isotope model Showed extracellular repletion with crystalloid essential for survival So? Does it work for trauma?

44 Not Really Trauma 44

45 The Three to One Rule Original studies Described three isotope model
Shires, 1963 Described three isotope model Showed extracellular repletion with crystalloid essential for survival

46 Fluid 3:1 Rule Developed in “controlled hemorrhage” model
NEVER tested in people Pre-dated EMS and Trauma Systems Became “doctrine” without any class I, II, or III data

47 NOW Call Surgeon RESUSCITATION ? Historic Assessment
A - ALL IVs FULL Flow B – BP higher than normal C – Chart Looks good NOW Call Surgeon Trauma 47

48 HISTORIC AMAZING -Patient’s surgery DELAYED until “resuscitated” in EMS, EC, or ICU This is a NO NO Trauma 48

49 And NEW Problems happened
Vietnam experience Approach to hypotension was 2 large caliber IVs Give crystalloid as rapidly as possible. And NEW Problems happened

50 Resuscitation Courses ATLS ACLS PALS (12 others)
Almost identical cirriculum Teach ABCs Encourage FLUID bolus Lots of Urban Legends Trauma

51 “Fill the tank” “Fluid Challenge”
Commonly quoted phrases Trauma 51

52 Three Peaks in Mortality
Lethal MOF Early “resuscitation” Pop the Clot Early fluid type DOES effect Death & MOF

53 Residual, quiet continuing questions (Did not join bandwagon)

55 Permissive Hypotension
1980s and 1990s- rodent & swine models of hemorrhagic shock Aggressive fluid resuscitation in uncontrolled hemorrhage resulted in increased mortality & morbidity Control of bleeding is essential for a successful treatment of hemorrhagic shock with 7.5 per cent sodium chloride solution. Rabinovici R, Krausz MM, Feuerstein G. Department of Surgery, Jefferson Medical College, Philadelphia, Pennsylvania Surg Gynecol Obstet Aug;173(2): Small volume hypertonic saline (HTS) solution resuscitation has been shown to restore hemodynamic derangements and to protect against mortality in "controlled" hemorrhagic shock (CHS), but it exacerbates the shock state in "uncontrolled" hemorrhagic shock (UCHS). To study the mechanisms associated with the divergent outcome of HTS treatment in CHS versus UCHS, HTS was administered to anesthetized rats (n = 7) subjected to 15 per cent resection of the tail followed by controlled or uncontrolled bleeding. HTS treatment of UCHS increased bleeding (13.3 +/- 1.6 milliliters, p less than 0.05), dropped mean arterial pressure (MAP) ( /- 8.9 millimeters of mercury, p less than 0.001), central venous pressure (zero millimeters of mercury, p less than 0.001) and cardiac index (CI) (41 per cent of basal value, p less than 0.001) and increased acidosis (pH /- 0.12, p less than 0.05) and mortality (mean survival time 75 +/- 15 minutes versus 122 +/- 23 minutes of untreated rats, p less than 0.05). In contrast, when administered after application of a ligature proximal to the resection site (at 15 minutes), HTS completely reversed the changes in MAP, CI and total peripheral resistance index (TPRI), and improved mean survival time (172 +/- 7 minutes, p less than 0.05). These data support the assumption that HTS should be used in the treatment of hemorrhagic shock only after bleeding was controlled. The detrimental effects of intravenous crystalloid after aortotomy in swine. Bickell, WH, Brutting SP, Millnamow GA, O?Benar J, Wade CE Division of Military Trauma Research, Letterman Army Institute of Research, Presidio of San Francisco, CA Surgery 1991 Sep;110: Comment in: Surgery Sep;110(3):573-4 We tested the hypothesis that, after aortotomy, rapidly replacing three times the blood volume deficit with intravenous crystalloid will increase hemorrhage and decrease survival. Sixteen anesthetized Yorkshire swine underwent splenectomy and stainless steel wire placement in the infrarenal aorta and were instrumented with pulmonary artery and carotid artery catheters. The wire was pulled, producing a 5 mm aortotomy and spontaneous intraperitoneal hemorrhage. The animals had been alternately assigned to either an untreated control group (n = 8) or a treatment group (n = 8), which received 80 ml/kg lactated Ringer's solution intravenously. The volume of hemorrhage and the mortality rate were significantly increased (p less than 0.05) in the treatment group receiving lactated Ringer's solution relative to the control animals ( ml versus ml, and eight of eight animals versus zero of eight animals, respectively). From these data we conclude that, in this model of uncontrolled arterial hemorrhage resulting from abdominal aortotomy, rapidly administering lactated Ringer's solution intravenously significantly increases hemorrhage and death. Effect of blood pressure on hemorrhage volume and survival in a near-fatal hemorrhage model incorporating a vascular injury. Stern, SA Dronen SL, Birrer P. et al. Department of Emergency Medicine, University of Cincinnati College of Medicine, Ohio. Ann Emerg Med 1993 Feb;22 :155. Comment in: Ann Emerg Med Feb;22(2):225-6 STUDY HYPOTHESIS: In a model of near-fatal hemorrhage that incorporates a vascular injury, stepwise increases in blood pressure associated with aggressive crystalloid resuscitation will result in increased hemorrhage volume and mortality. DESIGN: This study used a swine model of potentially lethal hemorrhage in the presence of a vascular lesion to compare the effects of resuscitation with mean arterial pressures of 40, 60, and 80 mm Hg. Twenty-seven fully instrumented immature swine (14.8 to 20 kg), each with a surgical-steel aortotomy wire in place, were bled continuously from a femoral artery catheter to a mean arterial pressure of 30 mm Hg. At that point the aortotomy wire was pulled, producing a 4-mm aortic tear and uncontrolled intraperitoneal hemorrhage. When the animal's pulse pressure reached 5 mm Hg, the femoral artery hemorrhage was discontinued and resuscitation was begun. INTERVENTIONS: Saline infusion was begun at 6 mL/kg/min and continued as needed to maintain the following desired endpoints: group 1 (nine) to a mean arterial pressure of 40 mm Hg, group 2 (nine) to a mean arterial pressure of 60 mm Hg, and group 3 (nine) to a mean arterial pressure of 80 mm Hg. After 30 minutes or a total saline infusion of 90 mL/kg, the resuscitation fluid was changed to shed blood infused at 2 mL/kg/min as needed to maintain the desired mean arterial pressure or to a maximum volume of 24 mL/kg. Animals were observed for 60 minutes or until death. MEASUREMENTS AND MAIN RESULTS: Data were compared using repeated-measures analysis of variance with a post hoc Tukey-Kramer, Fisher's exact test, and Kruskal-Wallis. Mortality was significantly greater in group 3 (78%) compared with either group 1 (11%; P = .008) or group 2 (22%; P = .028). Mean survival times were significantly shorter in group 3 (44 +/- 12 minutes) compared with either group 1 (58 +/- 6 minutes; P = .007) or group 2 (59 +/- 3 minutes; P = .006). The average intraperitoneal hemorrhage volumes were 13 +/- 14 mL/kg, 20 +/- 25 mL/kg, and 46 +/- 11 mL/kg for groups 1, 2, and 3, respectively (group 1 versus 2, P = .425; group 1 versus 3, P < .001; group 2 versus 3, P = .014). Group 2 animals demonstrated significantly greater oxygen deliveries compared with groups 1 and 3. CONCLUSION: In a model of near-fatal hemorrhage with a vascular injury, attempts to restore blood pressure with crystalloid result in increased hemorrhage volume and markedly higher mortality.  Prospective evaluation of preoperative fluid resuscitation in hypotensive patients with penetrating truncal injury: a preliminary report. Martin RR. Bickell WH. Pepe PE. Burch JM. Mattox KL. Cora & Webb Mading Department of Surgery, Baylor College of Medicine, Houston, Texas Journal of Trauma Sep;33(3):354-61; discussion 361-2, Although intravenous (IV) fluid therapy is routinely prescribed for hypotensive injury victims, there are concerns that elevating the blood pressure before hemorrhage is controlled may be detrimental. This is a preliminary report of an ongoing randomized study designed to evaluate the effect fluid resuscitation, delayed until surgical intervention, has on the outcome for hypotensive victims of penetrating truncal injury. In the first year, 300 consecutive patients with gunshot or stab wounds to the trunk who had a systolic blood pressure of 90 mm Hg or less were entered into the study. Patients were excluded from the outcome analysis because of death at the scene or minor injury not requiring surgical intervention. The remaining study patients were randomized into (1) an immediate resuscitation group (n = 96) for whom IV fluid resuscitation was initiated in the ambulance and in the emergency center before surgical intervention, or (2) a delayed resuscitation group (n = 81) for whom IV fluid resuscitation was delayed until the time of surgical intervention. The two study groups were found to be well balanced with respect to anatomic injury severity, pretreatment vital signs, survival probability, and preoperative treatment times. There were no significant differences in the rate of survival to hospital discharge (immediate resuscitation group, 56%; delayed resuscitation group, 69%). There were no significant differences in the rate of postoperative complications. Further study is necessary to determine if it is advantageous to delay fluid resuscitation until surgical intervention.  Improved Outcome With Hypotensive Resuscitation of Uncontrolled Hemorrhagic Shock in a Swine Model Kowalenko T, Stern S, Dronen S, Wang X Department of Emergency Medicine, University of Cincinnati College of Medicine, Ohio. Journal of Trauma 1992 Sep;33(3):349,1992:349-53; discussion Recent animal studies have shown that aggressive saline infusion may produce significant mortality in models of moderately severe (20-30 mL/kg) uncontrolled hemorrhage. The postulated mechanism is an increase in hemorrhage that accompanies restoration of normal blood pressure. Although aggressive saline infusion and restoration of blood pressure appear indicated when hemorrhage is potentially lethal (40-45 mL/kg), we hypothesized that the attempt to restore blood pressure with aggressive saline infusion would not improve survival. This study used a swine model of severe uncontrolled hemorrhagic shock to compare the effects of resuscitation to mean pressures of 40 and 80 mm Hg. Twenty-four immature swine, each with a surgical steel aortotomy wire in place, were bled rapidly from a femoral artery catheter to a mean arterial pressure (MAP) of 30 mm Hg. The aortotomy wire was then pulled, producing a 4-mm aortic tear and free intraperitoneal hemorrhage. When the pulse pressure decreased to 5 mm Hg, saline infusion was begun at 6 mL/kg/minute and continued as needed to maintain the following endpoints: group I (MAP = 40 mm Hg), group II (MAP = 80 mm Hg), and group III (no resuscitation). After a maximum saline infusion of 90 mL/kg, the infusate was changed to shed blood at 2 mL/kg/minute. Data were compared using analysis of variance and Fisher's exact test. One-hour survival was 87.5%, 37.5%, and 12.5% for groups I, II, and III, respectively. Intraperitoneal hemorrhage for the three groups was 8.2 mL/kg, 39.9 mL/kg, and 6.7 mL/kg. The amount of saline infused was 55.8 mL/kg in group I and 90 mL/kg in group II.
