Abstract

Introduction

In recent decades, advances in surgical skills and surgical devices have increased the efficacy of surgery, and reduced the associated morbidity and mortality risks. However, surgeons still face many challenges such as uncontrolled hemorrhage, which remains a life-threatening scenario. The “bloody vicious cycle,” comprises coagulopathy, acidemia, and hypothermia, and this triad augments and exacerbates physiological instability [1]. It may not be feasible for surgeons to repair all identified injuries during the initial operation, and a decision may be made to complete the surgery with a 2^nd procedure. However, in cases of uncontrolled bleeding, gauze packing can be useful to provide surgeons with the time needed to repair reversible physiological derangements, such as acidemia, hypothermia, and coagulopathy, which may result from prolonged surgical time and transfusion therapy.

Gauze packing can be used to control massive hemorrhage in trauma patients and in a range of severe conditions, such as liver damage, abdominal aortic aneurysm rupture, postpartum bleeding, and pelvic bleeding [2–6]. However, there are few reports of the use of gauze packing in non-trauma patients and patients without liver injury. Therefore, the aim of this study was to evaluate the outcome of non-trauma patients who required intra-abdominal gauze packing for surgically uncontrollable hemorrhage and determine the risk factors for survival.

Materials and Methods

Data from 28 patients who underwent intrabdominal gauze packing to manage uncontrollable hemorrhage during abdominal surgery at the Asan Medical Center between September 2012 and March 2019 were evaluated. The gauze packing performed in all 28 cases was carried out by a single surgeon who used the standardized gauze packing procedure. Trauma patients and 2 patients who died during surgery or within 1 hour after surgery due to bleeding were excluded from the study population because these cases were considered as “death during surgery.” Records were reviewed for clinical characteristics (including age, sex, comorbidity, elective or emergency surgery, amount of transfusion, and number of packing gauzes used); laboratory findings were also reviewed. The primary endpoint was mortality at discharge from hospital to evaluate the survivor group and non-survivor group. The study protocol was approved by the Institutional Review Board of the Asan Medical Center (IRB no.:2019-1013). Due to the retrospective nature of this study informed consent was waived.

Results

Data from 28 patients were included in the analysis of the study population. The etiology of abdominal hemorrhage is listed in Table 1. The clinical and laboratory characteristics of the patients are summarized in Table 2. There were no differences in age, sex, number of transfused blood components during surgery, or number of gauzes used between the survivor and non-survivor groups. Furthermore, there were no differences in laboratory findings (platelet count, C-reactive protein, and lactic acid) just prior to gauze removal between the 2 groups. However, the non-survivor group contained more immunocompromised patients (transplant patients, and patients with cytopenia as a result of chemotherapy), thrombocytopenia patients, and those patients requiring a longer duration to gauze removal.

The clinical and laboratory findings following gauze packing and prior to gauze removal are summarized in Table 3. The mean surgical time required for gauze removal was 105 ± 71 minutes. Nineteen (70.4%) of 27 patients only underwent gauze removal. Eight (29.6%) of 27 patients underwent additional tumor resection or bowel resection and anastomosis during gauze removal surgery.

A total of 9 patients died during hospitalization (median survival, 38 days; range, 0–138 days), with only 1 patient dying as a result of uncontrolled bleeding. The cause of death in the remaining patients was uncontrolled infection (n = 6), bowel ischemia (n = 1), and disease recurrence (n = 1). Three of the total deaths were recorded in the 1st month after gauze packing.

In spite of gauze packing, 2 patients who had consistently increased blood transfusion requirements (> 4 packs/4 hours) were found to have arterial bleeding. The 1st patient was a 68-year-old female with a 30 × 25 cm mass in the left side her abdomen. In the 1st operation, the patient underwent excision of the mass within the left kidney and the patch aortoplasty technique was applied. Despite transfusion with 6 units of pRBCs and 8 units of fresh frozen plasma (FFP) over 4 hours, the patient’s vital signs remained unstable. Therefore, gauze packing was inserted during a 2nd operation. Following surgery, despite previously receiving 8 units of pRBCs and 4 units of FFP, this patient still required transfusions. An enhanced abdominopelvic computed tomography (CT) scan showed extravasation of contrast from the splenic artery branch, and a 3rd operation was performed to control the bleeding with suture ligation and repeat gauze packing (Figure 1). After 36 hours, the bleeding had stopped, and the gauze was removed. The patient remains alive to date. The 2nd patient was an 86-year-old male with anastomosis failure and ischemic enterocolitis. The patient underwent jejunal segmental resection with jejunostomy because of anastomosis failure and left hemicolectomy with splenectomy due to ischemic colitis and spleen injury. After the 1st operation, the patient received 17 units of pRBCs and 20 units of FFP over 7 hours; with the consent of the patient’s family, gauze packing was performed in the ICU. However, despite this, 14 units of pRBCs and 10 units of FFP were required over 16 hours. Enhanced abdominopelvic CT scan showed extravasation of contrast from the splenic artery branch (Figure 2). Due to the patient’s poor physical condition, bleeding had to be controlled by embolization, which was successful. However, the patient died 45 days later as a result of an uncontrolled infection.

In the univariate analysis, immunocompromised patients, emergency surgery, a thrombocytopenic state before the initial surgery, and a longer duration until gauze removal were determined to have an impact on survival outcome. Among these factors, only a duration of > 36 hours to gauze removal was determined to be an independent risk factor for survival in the multivariate analysis (Table 4).

Discussion

Compression has long been used as a simple and effective method of hemostasis. Therefore, gauze packing is commonly used in a range of cases from simple epistaxis and wound bleeding to massive bleeding as a result of trauma. Gauze packing of the abdomen has been recognized as a useful intervention in the management of trauma patients with massive hemorrhage [7–9]. The pathogenesis of the “bloody vicious cycle” is complex and results from massive transfusion, persistent cellular shock and clotting factor deficiencies, promoting and exacerbating hypothermia, acidosis, and coagulopathy [1]. Sharp et al identified that acidosis (pH ≤ 7.18), hypothermia (temperature ≤ 33°C), coagulopathy (prothrombin time ≥ 16 seconds, thromboplastin time ≥ 50 seconds), and massive transfusion (≥ 10 units) were risk factors for poor outcome [6]. The major goal of intra-abdominal gauze packing is to break the “bloody vicious cycle” and to restore normal physiological parameters. The use of gauze packing to halt severe hemorrhage during abdominal surgery is also thought to be plausible in non-trauma patients where it can be a life-saving modality.

Intra-abdominal packing, particularly peri-hepatic gauze packing, is an accepted technique for the control of hemorrhage following severe hepatic trauma [10,11]. A recent study reported that this approach was highly effective in achieving hemostasis during liver transplantation surgery [3]. Gauze packing has also been shown to be highly effective for the management of hemorrhage from large retroperitoneal veins [12,13]. In the current study, gauze packing was a very useful method of controlling paravertebral venous plexus bleeding (Figure 3) and retroperitoneal vein bleeding [12]. In obstetrics, intrauterine gauze or abdominopelvic gauze packing is a life-saving method for controlling postpartum bleeding [13–15]. Hemostasis through gauze packing has recently been reported in patients with ruptured abdominal aortic aneurysm repair or severe thoracic trauma [2,16,17].

The decision to perform gauze packing is a difficult one, and the timing is controversial. The indications for damage control surgery for abdominal trauma are generally hemorrhagic shock due to intra-abdominal bleeding with acidosis, coagulopathy, and hypothermia (the lethal triad), or a condition worsening progressively toward the lethal triad of conditions [12,17]. However, there are no specific guidelines for gauze packing in non-trauma patients. Furthermore, unlike trauma patients, gauze packing in non-trauma patients is characterized by less severe hypothermia and acidosis, because gauze packing is performed before hypothermia or acidosis becomes severe. In the current study, hemostasis was attempted in patients with no preoperative problems rather than gauze packing after ≥ 10 pRBCs units had been transfused. However, in the case of thrombocytopenia and/or preoperative prolongation of prothrombin time, if oozing bleeding was observed, gauze packing was considered rather than hemostasis. It is important to make appropriate and quick decisions on whether to perform gauze packing based on the patient’s condition.

The packing technique involves the use of dry gauzes placed directly over the injury by exerting pressure and compressing bleeding points against bone or fascia in cases involving the pelvis, paravertebral site, or retroperitoneal venous bleeding. In the case of diffuse oozing bleeding or bleeding over a large area, dry gauzes are placed over the dissected area with the abdomen closed under tension to provide tamponade. However, the risk of abdominal compartment syndrome must be considered if too much pressure is applied. The patient population of this study were non-trauma patients, therefore severe bowel edema rarely occurred. So abdominal compartment syndrome rarely occurred. If bleeding persists despite adequate packing, arterial bleeding or large vessel injury should be suspected. In the present study, 2 patients had persistent bleeding after packing, and an enhanced CT scan revealed evidence of arterial bleeding. If the patient’s vital signs are maintained, it may be more helpful to consider a 2nd operation after an enhanced CT scan.

When the patient’s vital signs are hemodynamically stable, and hypothermia and coagulopathy have been corrected, then, gauze removal surgery should be considered. Prior to removing the gauze, it is essential to moisten the gauze packing area to avoid re-bleeding. Gauze removal has been recommended within 12–36 hours following the initial surgery [7,18]. One study has shown that removing perihepatic packs 36–72 hours after gauze packing reduced the risk of re-bleeding without increasing the risk of liver-related complications in hepatic injury patients [10]. Abikhaled et al [19] reported that higher rates of abscess formation and mortality were observed if packed gauzes were left in place for > 72 hours. We noted 2 cases of which pigtail catheter insertion was required for drainage of an intra-abdominal abscess. Nevertheless, the pigtail catheter insertion was performed 2–3 weeks after gauze removal which makes it difficult to infer that the abscess was due to gauze packing. Thus, there was no notable abscess formation directly caused from gauze packing in our study.

In the current study, 20 of 27 patients (74%) underwent successful gauze removal within 36 hours of the index operation without re-bleeding. Six of the 7 patients (85.7%) who underwent gauze packing removal after 36 hours died, which was determined to be a significant risk factor in the multivariate analysis. This may be related to the poor general condition of the patients before the index operation, which made the correction of coagulopathy challenging, and delayed the timing of gauze removal. We can presume that the patients’ poor general conditions also prevented their recovery.

In conclusion, gauze packing is a very effective approach to the management of uncontrolled hemorrhage in non-trauma patients. In cases of persistent bleeding after gauze packing, arterial bleeding should be suspected. A delay in gauze removal of > 36 hours can lead to poor survival outcomes.
