Packing the chest: a useful technique for intractable bleeding after open heart operation

Principles of minimize bleeding and the transfusion of blood and its components in operated patients - surgical aspects

One of the target of perioperative tratment in surgery is decreasing intraoperative bleeding, which increases the number of perioperative procedures, mortality and treatment costs, and also causes the risk of transfusion of blood and its components. Trying to minimize the blood loss(mainly during the operation) as well as the need to transfuse blood and its components (broadly understood perioperative period) should be standard treatment for a patient undergoing a procedure. In the case of this method, the following steps should be taken: 1) in the preoperative period: identyfication of risk groups as quickly as possible, detecting and treating anemia, applying prehabilitation, modyfying anticoagulant treatment, considering donating one's own blood in some patients and in selected cases erythropoietin preparations; 2) in the perioperative period: aim for normothermia, normovolemia and normoglycemia, use of surgical methods that reduce bleeding, such as minimally invasive surgery, high-energy coagulation, local hemostatics, prevention of surgical site infection, proper transfusion of blood and its components if it occurs; 3) in the postoperative period: monitor the condition of patients, primarily for the detection of bleeding, rapid reoperation if required, suplementation (oral administration preferred) nutrition with microelements (iron) and vitamins, updating its general condition. All these activities, comprehensively and in surgical cooperation with the anesthesiologist, should reduce the blood loss and transfusion of blood and its components.

Delayed sternal closure for intractable bleeding after acute type A aortic dissection repair: outcomes and risk factors analyses

BACKGROUND

Perioperative coagulopathy and intractable bleeding are severe complications in acute type A aortic dissection (ATAAD) repair surgery. Mediastinal packing with delayed sternal closure (DSC) is a commonly adapted technique to stabilize the hemorrhagic tendency. This retrospective study aims to investigate the early and late outcomes and risk factors in patients who underwent DSC procedure during ATAAD repair surgery.

METHODS

This study investigated 704 consecutive patients who underwent ATAAD repair at this institution between January 2007 and September 2020. These patients were dichotomized into the DSC (n = 109; 15.5%) and primary sternal closure (PSC) groups (n = 595; 84.5%). The clinical features, surgical information, postoperative complications, 5-years cumulative survival, and freedom from reoperation rates were compared. A multivariate logistic regression analysis was used to identify the independent risk factors for patients who underwent DSC.

RESULTS

The DSC group showed a higher rate of hemopericardium and preoperative malperfusion, and was associated with longer cardiopulmonary bypass and aortic clamping times and a higher rate of intraoperative extracorporeal membrane oxygenation (ECMO) support. The DSC group showed higher blood transfusion volumes and rate of reexploration for bleeding after surgery. However, the in-hospital mortality rates (17.4% vs. 13.3%; P = 0.249), 5-year survival rates (66.9% vs. 68.2%; P = 0.635), and freedom from reoperation rates (89.1% vs. 82.5%; P = 0.344) were comparable between the DSC and PSC groups. Multivariate analysis revealed that hemopericardium, preoperative malperfusion, and intraoperative ECMO support were risk factors for implementing DSC.

CONCLUSIONS

DSC is an efficient life-saving technique to stabilize patients with intractable bleeding after undergoing ATAAD repair surgery, which leads to acceptable short- and long-term outcomes. Patients who were at risk for intractable bleeding should have early decision-making for implementing DSC.

Efficacy of platelet transfusion in cardiac surgery

Massive diffuse bleeding is still a problem in cardiovascular surgery. The first line treatment is platelet concentrate transfusion, although there is still insufficient information regarding efficacy, quantity, and timing. The objective of this prospective cohort study was to find out whether the amount of 4 apheresis platelet concentrates could reduce intraoperative bleeding and improve viscoelasticity and aggregometry.10 patients were enrolled intraoperatively because of life-threatening diffuse bleeding after cardiopulmonary bypass and received 4 apheresis platelet concentrates back-to-back. The units were given every 5 minutes. After every unit, thromboelastometry, performed by ROTEM®, and aggregometry, performed by Multiplate®, were done together with Hematocrit, Hemoglobin, and Platelet Count.Hematocrit and Hemoglobin showed a statistically significant decrease of 14%, whereas Platelet Count showed a statistically significant increase of 205%. MCE-EXTEM increased statistically significant: 46%. There was no statistically significant increase in both ADP and COL results.Even a series of 4 platelet concentrates did not comprehensively improve both essential components of an adequate hemostasis: viscoelasticity and aggregation. Just the transfusion of platelet concentrates alone did not build a sufficient strategy improving hemostasis and reducing bleeding. A positive effect of surgical packing on stopping the bleeding could be seen.

Abdominal and thoracic wall closure: damage control surgery's cinderella

Damage control surgery principles allow delayed management of traumatic lesions and early metabolic resuscitation by performing abbreviated procedures and prompt resuscitation maneuvers in severely injured trauma patients. However, the initial physiological response to trauma and surgery, along with the hemostatic resuscitation efforts, causes important side effects on intracavitary organs such as tissue edema, increased cavity pressure, and hemodynamic collapse. Consequently, different techniques have been developed over the years for a delayed cavity closure. Nonetheless, the optimal management of abdominal and thoracic surgical closure remains controversial. This article aims to describe the indications and surgical techniques for delayed abdominal or thoracic closure following damage control surgery in severely injured trauma patients, based on the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia. We recommend negative pressure dressing as the gold standard technique for delayed cavity closure, associated with higher wall closure success rates and lower complication and mortality rates.

Thoracic compartment syndrome after penetrating heart and lung injury

Thoracic injuries are the most lethal penetrating injuries. After attempting suicide, two patients with a penetrating thoracic wound were admitted to our emergency department. During CT scan they became hemodynamically unstable, which is why we had to perform an emergency thoracotomy. In both cases, a perforation in the left ventricle as well as multiple lesions of the lung parenchyma and vessel injuries were found. After the treatment of the different injuries, a massive edema of the heart and lung prevented a primary closure of the thorax. Due to massive diffuse bleeding, a "packing" of the pleural cavity became necessary. To prevent a thoracic compartment syndrome, the thoracic wall was left open and the skin was closed with a plastic sheet. Due to the "open chest" procedure combined with "packing" of the thoracic cavity, the majority of patients with an edema of the heart and lung after a penetrating chest injury can be saved. Pitfalls of preclinical and clinical treatment, aspects of diagnostics and surgery are discussed.

Delayed Cardiac Rupture Induced by Traumatic Myocardial Infarction: Consequence of a 45-Magnum Blast Injury; A Comprehensive Case Review

A penetrating chest trauma, a myocardial contusion or a myocardial infarction can lead to a cardiac rupture, which is linked to an extreme high death rate. Only few cases with delayed perforation of the myocardium have been reported in literature. We report about a penetrating gunshot injury, which led to a myocardial contusion with secondary delayed rupture of the left ventricle and the left inferior lobe of the lung. The leakage of the lesion in the left ventricle could be sealed sufficiently with fibrin-coated collagen fleeces after adapting stitches with Prolene 2-0. For additional stabilization of the vulnerable myocardium area, a bovine patch has been placed on the damaged ventricle. Fibrin fleeces are used successfully in cardiac surgery, as in our case, to seal the leakage of the lesion in the left ventricle. The implantation of a bovine patch in the pericardium could prevent a cardiac compartment syndrome with a fatal pericardial tamponade. To prohibit a thoracic compartment syndrome a modified Bogota bag could be sewed in for temporarily closure of the chest. In most cases penetrating cardiac injuries can be treated without heart-lung-machines. An immediate transfer to a cardio-surgical center is, due to the acute situation, not possible. If a surgeon with thoraco-surgical expertise is present a transfer is not absolutely necessary.

Mediastinal Packing for Intractable Coagulopathy in Acute Aortic Dissection (Types 1 and 2 DeBakey): A Life-Saving Technique-Report of Experiences

Nonsurgical bleeding after complex thoracic aortic procedures (such as aortic dissection and aortic aneurysm) is a great challenge for cardiac surgeons because of severe coagulopathy, exsanguinous bleeding, and inevitable death. Temporary mediastinal packing (with sponge) in such cases is the only life-saving technique with good result in most cases. Herein, we presented three cases with acute aortic dissection with intractable bleeding that was successfully managed with mediastinal packing.

Damage Control for Thoracic Trauma

Damage control surgery involves an abbreviated operation followed by resuscitation with planned re-exploration. Damage control techniques can be used in thoracic trauma but has been infrequently reported. Our goal is to describe our experience with the use of damage control techniques in treating thoracic trauma. A retrospective analysis of all patients undergoing damage control thoracic surgery related to trauma from January 1, 2010, to January 1, 2013, at University of Louisville Hospital, a Level I trauma center. Variables studied included injury characteristics, Injury Severity Score, surgery performed, duration of packing, length of stay (LOS), ventilator days, transfusion requirements, complications, and mortality. Twenty-five patients underwent damage control surgery in the chest with packing, temporary closure, and planned re-exploration after stabilization. Seventeen patients underwent anterolateral thoracotomy, and eight patients underwent sternotomy. The mean LOS and duration of temporary packing was 20.6 and 1.4 days in the thoracotomy group, respectively, and 19.5 and 1 day in the sternotomy group, respectively. The overall mortality rate was 40 per cent, 35 per cent in the thoracotomy group and 50 per cent in the sternotomy group. Like in severe abdominal trauma, damage control techniques can be used in the management of severe thoracic injuries with acceptable results.

A novel chest packing technique for intractable bleeding after open heart surgical procedures

Intractable bleeding after cardiac surgical procedures is a life-threatening complication. In most cases, the main bleeding site is present in the retrosternal space, not the pericardial space. Packing the chest may be a useful technique for achieving hemostasis. Herein, we describe a novel and effective procedure for the treatment of intractable bleeding in the retrosternal space using a sheet of oxidized regenerated cellulose and sponges after cardiac surgical procedures.

[Temporary treatment of uncontrolled intrathoracic hemorrhaging with abdominal towels in combination with a rescue procedure. Damage control procedure of the chest]

Case report of a 27-year-old patient who presented with a stab wound in the posterior aspect of the right chest. The patient was physiologically unstable and not responding to fluid resuscitation. A right intercostal drainage was inserted which immediately drained 1100 ml of blood. Thoracotomy was performed where a large clot was removed from the pleural cavity and followed by massive bleeding from the hilum of the lung as well as an intercostal artery posteriorly. Control of the hilar hemorrhaging necessitated right middle lobe resection. Attempts to control the bleeding from the intercostal artery were futile becoming technically more difficult due to a comminuted fracture of the ribs at the site of entry of the knife. During these attempts the patient became moribund. As a last resort the pleural cavity was packed with abdominal towels and the patient was transferred to the intensive care unit (ICU). The patient was returned to surgery after 48 h at which time the packing was removed with no further bleeding. On day 11 postoperatively drainage of the pleural collection was carried out and decortication of the right lower lobe. The patient was discharged 23 days after admission in a good general condition. This case report demonstrates that in exceptional circumstances packing of the pleural cavity to control bleeding can be considered as a method of damage control in penetrating chest trauma.

Packing of renal fossa: useful technique for intractable bleeding after open pyelolithotomy surgery

There is no documented study to indicate the role of prolonged packing of renal fossa (24 to 48 hours) to control bleeding in life threating haemorrhage following open pyelolithotomy without compromise in the renal functions. On the contrary emergency nephrectomy was performed for intractable bleeding during renal stone surgery in peripheral hospitals. Several studies have shown the usefulness of temporary packing to control bleeding in liver injuries and following open heart operations. Packing of the renal fossa with laparotomy pads in unstable patients, and transferring the patient to the surgical intensive care unit (ICU) is also described in trauma but not in controlling bleeding after open pyelolithotomy. This study comprises of three such patients whose kidneys were salvaged by a simple procedure of temporary packing of renal fossa for period of 24-48 hours who had developed life threatening haemorrhage after open pyelolithotomy. This technique is simple and worth trying especially for surgeons who are contemplating nephrectomy as prolonged packing has not lead to any compromise in renal functions. The aim of this manuscript is very limited and clear. Packing is not a licence to carry out open pyelolithotomy without proper expertise and local backup or resources. Principles of safe and ethical surgical practice should never be violated as it can lead to medico legal complications.

Does temporary chest wall closure with or without chest packing improve survival for trauma patients in shock after emergent thoracotomy?

BACKGROUND

Many surgeons avoid the damage-control techniques of intrathoracic packing and temporary chest wall closure after thoracotomy for trauma because of concerns about packing's effects on intrathoracic pressure and infectious risks. We hypothesized that temporary chest closure with or without intrathoracic packing (TCC-P) as a method of thoracic damage control would yield higher than expected survival rates for trauma thoracotomy patients with metabolic exhaustion, whereas traditional definitive chest closure (DEF) would exhibit predicted survival rates.

METHODS

This was a retrospective cohort study by two urban Level I trauma centers on patients who (1) underwent emergent thoracotomy for trauma, (2) received ≥10 units (U) packed red blood cells and/or sustained a cardiac arrest before starting chest closure, and (3) survived to intensive care unit arrival. Demographic/physiologic data, chest closure method, and thoracic complications were gathered. Trauma injury severity scores (TRISS) were used to calculate survival probability for TCC-P and DEF. Nonparametric statistics were used for all comparisons. All values are expressed as medians and interquartile ranges (IQR).

RESULTS

Sixty-one patients met inclusion criteria. Both TCC-P (n = 17) and DEF (n = 44) were severely injured (ISS=35 [IQR, 25-42] vs. 29 [IQR 19-45] and packed red blood cells = 16.5 U [IQR, 12.3-25.5 U] vs. 15 U [IQR, 11-23 U], respectively; p=ns). Patient demographics were similar except for the findings that the TCC-P cohort had higher rates of cardiac arrest before starting chest closure (TCC-P 82% vs. DEF 48%, p=0.04), significantly more severe abdominal injuries, and less severe head injuries than the DEF group. No significant differences were observed in survival of the overall samples (TCC-P=47% vs. DEF=57%), nor for observed:expected (O:E) survival ratio in 13 patients with TCC-P and 30 with DEF meeting criteria for TRISS calculation (TCC-P O:E, 46%:39%; DEF O:E, 53%:57%). No significant differences were found for TCC-P and DEF thoracic infectious (24% vs. 25%) or hemorrhagic (18% vs. 14%) complications. Surprisingly, peak inspiratory pressures on intensive care unit arrival were markedly better after TCC-P (20 cm H2O [IQR, 18-31 cm H2O]) than after DEF (32.5 cm H2O [IQR, 28-37.5 cm H2O], p=0.003).

CONCLUSION

Concerns about TCC-P are not borne out as thoracic infection rates are unaffected and peak pressures are actually lower, possibly due to greater pleural volume from an open chest wall and skin-only closure. However, no significant survival benefit was seen with TCC-P.

The control of severe intraoperative bleeding using an overlay autogenous tissue (OAT) patch: case reports

BACKGROUND

Severe intraoperative bleeding cannot always be controlled by standard surgical techniques. We recently reported a new technique to repair serious vascular injury using a free graft of omentum or rectus abdominus fascia as an overlay autogenous tissue (OAT) patch in the experimental sheep model. We now describe the successful clinical use of this patch in three patients.

CASE REPORTS

Radical surgery was performed on three patients with pelvic malignancy with resulting uncontrollable bleeding from the internal iliac vein, pelvic side wall and paravaginal venous plexuses, respectively. Hemostasis was secured using an OAT patch made of abdominus rectus fascia in two cases and appendix epiploicae as an omental substitute in the other.

DISCUSSION

The utility of the OAT patch is described in three different clinical situations. It is suggested that this technique may be especially useful to gynecologic oncologists when standard surgical techniques fail to control bleeding or there is limited access to the site of injury.

Thoracic Packing for Uncontrolled Bleeding in Penetrating Thoracic Injuries

We present a series of three patients who suffered penetrating thoracic injury, and in whom thoracic packing was used as a life-saving procedure. Survival among these patients paralleled the severity and extent of the original injuries. Restriction of cardiac filling and lung expansion are potential deterrents from using this technique; however, its use seems to be a valid adjunct, especially in the setting of chest wall bleeding coming from the intercostal arteries. Damage control surgery in pentrating thoracic trauma, including thoracic packing, is a sound alternative when uncontrollable bleeding, hypothermia and coagulopathy compromises the survival of a patient.

Avoidance of Bleeding During Surgery in Patients Receiving Anticoagulant and/or Antiplatelet Therapy

Perioperative management of chronically anticoagulated patients and/or patients treated with antiplatelet therapy is a complex medical problem. This review considers the pharmacokinetic and pharmacodynamic properties of commonly used antiplatelet and anticoagulant drugs with special emphasis on loss of effects after discontinuation and possible counteracting (or antidote) strategies. These drugs are aspirin (acetylsalicylic acid), ticlopidine/clopidogrel, abciximab, tirofiban and eptifibatide, heparin (unfractionated and low-molecular-weight), warfarin and direct thrombin inhibitors. Since the pharmacological mechanisms of some of these drugs are based on irreversible or slowly reversible effects, their pharmacokinetic profiles are not necessarily predictive for their pharmacodynamic profiles. A close and direct relationship between plasma concentrations and effects is seen only for the glycoprotein (GP) IIb/IIIa inhibitors tirofiban and eptifibatide with a fast off-rate for dissociation from the GPIIb/IIIa receptor, and for direct thrombin inhibitors (hirudin and argatroban). For other compounds, drug concentrations in plasma and pharmacodynamic effects are not closely correlated because of, for example, irreversible binding to their target (aspirin, clopidogrel and abciximab), inhibition of the generation of a subset of clotting factors with differing regeneration and degradation rates (coumarins) or sustained binding to the vascular wall (heparins). Surgery in patients on anticoagulant and/or antiplatelet therapy may be categorised as: (i) elective versus urgent; and (ii) cardiopulmonary bypass (CPB) versus non-CPB. Monotherapy with clopidogrel or aspirin need not be discontinued in elective non-CPB surgery, and temporary discontinuation of warfarin should be accompanied by preoperative intravenous heparin only in selected high-risk patients. Vitamin K as an antidote for warfarin should only be used subcutaneously and solely in urgent/emergency surgery. In elective surgery requiring CPB (coronary artery bypass grafting), it is recommended to discontinue aspirin 7 days preoperatively in patients with a low risk profile. Patients requiring urgent CPB surgery (e.g. after failure of a percutaneous coronary angioplasty with or without coronary stent deployment) are usually pretreated with several antiplatelet agents (e.g. aspirin and clopidogrel, together with a GPIIb/IIIa inhibitor) together with unfractionated or low-molecular-weight heparin. With judicious planning, urgent/emergency cardiac surgery can be safely performed on these patients. Delaying surgery (e.g. for 12 hours in patients treated with abciximab) should be considered if possible. Standard heparin doses should be given to achieve optimal anticoagulation for CPB. Prophylactic use of aprotinin (intra- and/or postoperatively), aminocaproic acid or tranexamic acid should be considered. Early (in the operating theatre prior to chest closure) and judicious use of replacement blood products (platelets) should be commenced when clinically indicated.

Pedicled pericardial fat pad: a useful hemostatic supplement

Control of bleeding in areas difficult to suture because of tissue friability, edema, or calcification poses a serious problem in cardiac surgery patients. We report the use of a pedicled pericardial fat pad as an adjunct to the control of bleeding in these difficult-to-suture areas. This technique was used in 9 patients who were bleeding from different areas (the atria, coronary sinus, aorta, and myocardium), and the bleeding was completely and easily controlled. We consider the pedicled pericardial fat pad to be a useful supplement when suturing alone cannot effectively bring the bleeding under control.
