Initial Resuscitation in Surgical Emergencies
The document discusses the initial steps in resuscitation for surgical emergencies, including assessing and treating the ABCDEs (airway, breathing, circulation, disability, exposure/environment). It covers open airway methods, types of airway equipment, needle decompression for tension pneumothorax, chest seals for open pneumothorax, and classifications of shock. Pathophysiology of hemorrhagic shock is explained in terms of cardiovascular, hormonal, microcirculatory responses. Fluid resuscitation is discussed, including types of fluids, ideal properties, and evolution of resuscitation solutions. Blood transfusion components like packed red blood cells, plasma
24. Historical Background
Walter B. Cannon, 1918
• World War I
• “Toxic factor”
• “ Restoration of blood
pressure prior to control of
active bleeding may result in
loss of blood that is sorely
needed.”
25. Historical Background
Alfred Blalock, 1934
• Reduce cardiac output due to
volume loss, not a “toxic
factor”
Categories of shock
• Hypovolemic shock
• Vasogenic shock
• Neurogenic shock
• Cardiogenic shock

51. Evolution of Fluid Resuscitation
1831: 1st Cholera pandemic
•William Brooke
O’Shaughnessy
•Injection of high oxygenated
salt into the venous system
•0.5-1% NaCl: Indifferent
solution
52. Evolution of Fluid Resuscitation
1892 Spencer “normal saline”

• 0.92% saline was normal
• Isotonic to human serum
1883 Sydney Ringer
•0.75%saline in pipe water for

54. Ideal Resuscitation Fluid
The ideal resuscitation fluid would have to have the
properties of an elixir of life: a small-volume cocktail
that among its virtues improves perfusion, enhances
oxygen (O2) delivery and diffusion, provides adequate
metabolic substrates, neutralizes toxic molecules
released as a result of tissue injury, provides
antimicrobial activity, renders the recipient globally
less vulnerable to the effects of hemorrhagic shock,
and has prolonged beneficial effects. The solution
should further be stable for lengthy periods at a variety
of temperatures, be easy to prepare and administer,
and, if not inexpensive, be at least affordable
57. Crystalloids: 0.9% Saline
• 9 g sodium chloride in 1 L water
• Osmolarity 308 mOsm/L
• pH 5
• Na 154 mEq/L, Cl 154 mEq/l
“Abnormal saline”
• Fluid retention
• Hyperchloremic metabolic acidosis
• Activation of neutrophils
58. Crystalloids: Lactated Ringer’s Solution
• 6 g sodium chloride + 3.22 g sodium lactate
(racemic: D- and L-lactate) + 400 mg potassium
chloride + 270 mg calcium chloride in 1 L water
• Osmolarity 275 mOsm/L
• pH 6.5
• Vietnam conflicts: DaNang lung, shock lung,
Traumatic wet lung…ARDS
• Neutrophils activation
• Increase ICAM-1
• Increase expression of Bax
59. Crystalloids: Hypertonic Saline
• De Felippe et al.1980; Velasco et al.,1980
• 7.5% sodium chloride
• Osmolarity 2567
• Small volume: Infusion of 250 mL, plasma volume
expansion 1000 mL
• Protect microcirculation
• Immunologic protection
• Kramer 1986: 7.5% saline with 6% Dextran 70
(Hypertonic saline-dextran, HSD)

64. Colloids: Conclusion
• Cochrane Injuries Group Albumin Reviewers,
CIGAR 1998: RR of death with albumin was 1.68
• CIGAR 2004: Fail to show benefit of colloid over
crystalloid
• Cochrane 2008: no evidence that one crystalloid
was safer than another, and because no
reduction in risk for death was evident in critically
ill patients, continued use of these agents in
these patients could not be justified outside the
setting of RCT Martin K Angele et al, Critical Care 2008;12(4)

Still on there way
69. Blood transfusion
• Fully crossmathed –> 1 hr or more
• Type specific –> 10-15 min
• Type O low titer Rh +/-
Stored blood ไม่ดีเท่า fresh blood เพราะ
: reduced oxygen carrying capacity (2,3-DPG)
: platelets are inactive
: clotting factors may be degraded
70. • Autotransfusion:
: directly anticoagulated and reinfused into
the patients using a macroaggregate filter.
: use of a cell-saver and provision of washed
RBCs.
• Massive transfusion:
: Transfusion of at least one blood volume or
10 units of blood in a 24 hr
71.
72. Whole blood:
• ประกอบด้วย colloids (plasma proteins), clotting
factors including platelets, red blood cells for
oxygen carrying capacity
• Indications: acute blood loss, concurrent
anemia and hypoproteinemia, clotting defects
• Dose 5 – 15 ml/kg/hr and 40-60 ml/kg/hr ( life-
threatening emergency. )
78. Cryoprecipitate
• Dose : 1U/5 kg เพิ่ม Fibrinogen 75 mg/dl
ให้ 10 U
: 1U/kg เพิ่ม 2% factor VIII activity
• Indication :
– Bleeding with fibrinogen < 100mg/dl เช่น DIC
– Von Willenbrand disease
– Hemophelia A
79. Complications การให้สารน้า
• Infection : local: swelling, redness, and fever ,
septicemia
• Phlebitis : irritation(foreign body (the IV
catheter)) or the fluids or medication
Symptoms : swelling, pain, and redness
Mx. warmth, elevation of the affected limb, or
a change flow rate
80. • Fluid overload : hypertension, heart failure,
and pulmonary edema
• Electrolyte imbalance
• Embolism
• A blood clot or other solid mass, or an air
bubble,
• Air bubbles < 30 mL dissolve into the
circulation harmlessly.
• Extremely large (3-8 mL/kg), Arrest
• Extravasation
81. Febrile non-hemolytic transfusion reaction
• most common ,benign
• fever and dyspnea 1 to 6 hours
Complication การรับผลิตภัณฑ์เลือด
Acute hemolytic reaction.
•Medical Emergency
•Hemolysis ของ donor RBC โดย host antibody.
•The most common “wrong unit to wrong patient”
•อาการ ไข้ หนาวสั่น ปวดหลัง ปัสสาวะสีชมพูแดง เหนื่อย หัวใจเต้นเร็ว ช็อก DIC ,
Renal failure
82. Management
• หยุดการให้เลือดทันที
• IV hydration ให้ปัสสาวะออกดี
• Oxygen
• ส่งเลือดในถุง และเลือดผู้ป่วยกลับไปตรวจซ้้า
• Hemolytic work up : Direct / Indirect coombs
test , CBC, Creatinine ,Coagulogram ,LDH
,Indirect bilirubin , Urine for hemoglobin
84. • Viral infection. : HBV( 1 in 250,000 units ) HIV or
HCV ( at 1 per 2 million units ).
• Bacterial infection. The risk is highest with
platelet transfusion (1 in 50,000 platelet
transfusions), and 1 in 500,000 red blood cell
transfusions
• Volume overload.
• Anaphylactic reaction.
86. Large Volume Crystalloid Resuscitation
• World War II: Blood for resuscitation lead to post-
traumatic ARF
• Vietnam: Large volume of crystalloid resuscitation
decreased incidence of ARF
• ATLS® protocol: 2L of crystalloid bolus and check
for response, if non-responder, call for blood
• Crystalloid: short term hemodynamic benefit,
adverse consequences of hemostasis
– Dilutional coagulopathy
– Secondary clot disruption
Increase blood flow
Increase perfusion pressure
Decrease blood viscosity
87. Immediate versus Delayed Fluid Resuscitation for
Hypotensive Patients with Penetrating Torso Injuries
William H. Bickell, Matthew J. Wall, Paul E. Pepe, R. Russell Martin,
Victoria F. Ginger, Mary K. Allen, and Kenneth L. Mattox
Among the 289 patients who received delayed fluid resuscitation, 203 (70
percent) survived and were discharged from the hospital, as compared with 193
of the 309 patients (62 percent) who received immediate fluid resuscitation (P =
0.04). The mean estimated intraoperative blood loss was similar in the two
groups. Among the 238 patients in the delayed-resuscitation group who survived
to the postoperative period, 55 (23 percent) had one or more complications
(adult respiratory distress syndrome, sepsis syndrome, acute renal failure,
coagulopathy, wound infection, and pneumonia), as compared with 69 of the 227
patients (30 percent) in the immediate-resuscitation group (P = 0.08). The
duration of hospitalization was shorter in the delayed-resuscitation group.
