Closed Suction Drainage after Total Knee Arthroplasty with Concomitant Intravenous Tranexamic Acid Administration.

Drain use in total knee arthroplasty (TKA) remains controversial. Use has been associated with increased complications, particularly postoperative transfusion, infection, increased cost, and longer hospital stays. However, studies examining drain use were performed before widespread adoption of tranexamic acid (TXA), which markedly reduces transfusion without increasing venous thromboembolism events. We aim to investigate incidence of postoperative transfusion and 90-day return to the operating room (ROR) for hemarthrosis in TKA with use of drains and concomitant intravenous (IV) TXA. Primary TKAs from a single institution were identified from August 2012 to December 2018. Inclusion criteria were primary TKA, age 18 years and over where use of TXA, drains, anticoagulant, and pre- and postsurgical hemoglobin (Hb) were documented during the patient's admission. Primary outcomes were 90-day ROR specifically for hemarthrosis and rate of postoperative transfusion. A total of 2,008 patients were included. Sixteen patients required ROR, three of which were due to hemarthrosis. Drain output was statistically higher in the ROR group (269.3 vs. 152.4 mL, p = 0.05). Five patients required transfusion within 14 days (0.25%). Patients requiring transfusion had significantly lower presurgical Hb (10.2 g/dL, p = 0.01) and 24-hour postoperative Hb (7.7 g/dL, p < 0.001). Drain output between the transfusion and no transfusion groups varied significantly (p = 0.03), with transfusion patients having higher postoperative day 1 drain output of 362.6 mL and total drain output of 376.6 mL. In this series, postoperative drain use with concomitant weight-based IV TXA is shown to be safe and efficacious. We observed exceedingly low risk of postoperative transfusion compared with prior reports of drain use alone as well as preserved low rate of hemarthrosis that has previously been positively linked to drain use.

Superior Capsule Reconstruction With Subacromial Allograft Spacer: Biomechanical Cadaveric Study of Subacromial Contact Pressure and Superior Humeral Head Translation.

PURPOSE: To investigate the biomechanical effects of superior capsule reconstruction with subacromial allograft spacer on superior humeral head translation and subacromial contact pressure. METHODS: Eight cadaveric shoulder specimens were tested in 4 conditions: (1) intact rotator cuff, (2) supraspinatus tear and superior capsule excision, (3) superior capsule reconstruction with human dermal allograft, and (4) superior capsule reconstruction with subacromial resurfacing using human dermal allograft. In each condition, specimens were tested at 0, 30, 60, and 90° of shoulder abduction in balanced and unbalanced loaded states for subacromial contact pressure and superior humeral head translation. Statistical comparisons were made using a repeated-measures analysis of variance test, followed by a Tukey post hoc test for pairwise comparisons. A P value <.05 was set as statistically significant. RESULTS: Superior humeral head translation and subacromial contact pressure were increased after irreparable rotator cuff tear (P = .001). There was no significant difference between superior capsule reconstruction and intact cuff in regard to superior humeral head translation and subacromial contact pressure at all abduction angles. Superior capsule reconstruction with subacromial resurfacing decreased superior humeral head translation relative to intact (0°, P = .004; 30°, P = .02; 60°, P = .08; 90°, P = .01), superior capsule reconstruction (0°, P = .001; 30°, P = .003; 60°, P = .019; 90°, P = .001), and cuff-deficient states (P = .001). Superior capsule reconstruction with subacromial resurfacing resulted in nonsignificant increases in subacromial contact pressure relative to intact cuff at 0 to 90° abduction angles. CONCLUSIONS: Superior capsule reconstruction with subacromial resurfacing using human dermal allograft results in decreased superior humeral head translation relative to superior capsule reconstruction with human dermal allograft only, while increasing subacromial contact pressure. CLINICAL RELEVANCE: Superior capsule reconstruction with subacromial resurfacing using human dermal allograft reduces superior humeral head translation while increasing subacromial contact pressure in a cadaveric model.

Application of an external fixator vascular compressor (EFVC) in the critically injured trauma patient: a novel damage control technique.

Methods of controlling hemorrhage in penetrating abdominal injuries are varied, ranging from electrocautery, ligation, laparotomy sponge packing, angiography, hemostatic agents, and direct manual pressure. Unfortunately, traditional methods are sometimes unsuccessful due to the location or nature of the hemorrhage, and manual pressure cannot be held indefinitely. We describe a novel damage control technique for hemorrhage control in these situations, followed by three cases where an external fixator vascular compressor (EFVC) was used to hold continual pressure. Three patients are presented to a Level 1 trauma center following multiple ballistic injuries, all requiring emergent exploratory laparotomy. The first had a two-pin iliac crest EFVC placed during repeat exploratory laparotomy to control bleeding. The second patient had a supra-acetabular EFVC placed during initial exploratory laparotomy after emergent embolization failed to control bleeding from the L3 vertebral body. The third patient had a two-pin iliac crest EFVC placed at initial exploratory laparotomy due to uncontrollable bleeding from the sacral venous plexus and internal iliac veins. Of the three patients, two stabilized and survived, while one passed away due to multi-organ failure. We describe a novel damage control technique that may be a useful means of temporarily stemming intraabdominal bleeding that is otherwise recalcitrant to traditional hemostatic methods. Additionally, we provided a limited case series of patients who have undergone this technique to illustrate its utility and versatility. This technique is simple, fast, effective, and adaptable to a variety of circumstances that may be encountered in patients with intraabdominal bleeding recalcitrant to conventional hemorrhage control.

Preferably Not My Surgery: A Survey of Patient and Family Member Comfort with Concurrent and Overlapping Surgeries.

BACKGROUND: Concurrent and overlapping surgical procedures are a timely topic. The 2 largest publications on the topic were limited to a journalistic overview and a government committee report. Since then, a recent survey of paid individuals found that they disapprove of overlapping surgical procedures in many cases. Still, we are aware of no work that specifically polled patients and their family members about their beliefs on concurrent and overlapping surgical procedures. We hypothesized that patients and family members will be uncomfortable with 1 surgeon performing overlapping or concurrent surgical procedures. METHODS: A survey about concurrent and overlapping surgical procedures was given to 200 patients and their family members at a single, urban academic medical center. Participants were asked to respond to questions about their knowledge of concurrent and overlapping surgical procedures, their comfort with different surgical scenarios, and their beliefs on possible reasons for such surgical scenarios. Individuals were approached about the survey until 200 patients and family members responded. RESULTS: On average, respondents were neutral with surgical procedures involving overlap of 2 noncritical portions and were not comfortable with overlap involving a critical portion of 1 or both surgical procedures. They agreed that hospitals allow overlapping surgical procedures to increase revenue. CONCLUSIONS: Patients undergoing a surgical procedure at an academic medical center and their family members were neutral or uncomfortable with concurrent or overlapping surgical procedures, affirming the hypothesis. Knowing these preferences is relevant to surgeons' practices and to informed consent discussions. It appears beneficial for surgeons to address the advantages and disadvantages of overlapping surgical procedures with their patients if applicable.

It All Depends on Who Does What: A Survey of Patient and Family Member Comfort With Surgical Trainees Operating.

OBJECTIVE: To measure patient and family member comfort with surgical trainees of varying levels performing different portions of surgery. DESIGN, SETTING, AND PARTICIPANTS: An electronic survey dividing surgery into 6 steps (prepping and positioning, initial incision, deep dissection, critical portions, deep suturing, and closing incision), differentiating surgical trainees by 4 levels of experience (medical student, intern, resident, and fellow), and specifying whether or not an attending surgeon is in the operating room (OR) was given to 200 patients and family members in the surgical waiting area of a single academic medical center. Responses were on a 7-point Likert scale from "Not Comfortable at All" to "Completely Comfortable". RESULTS: Patient and family member comfort significantly increased as trainee experience increased. It reached a nadir for all trainees performing "critical portions" of surgery. However, their average response was "Comfortable" for residents and fellows performing any surgical step when the attending surgeon is present in the OR. The percentage of "Comfortable" responses was significantly lower for all trainee levels performing any surgical step when the attending surgeon is absent from the OR. CONCLUSIONS: Patient and family member comfort with surgical trainees operating varies based on the trainee's level of experience, the step the trainee performs, and whether or not the attending surgeon is present in the OR. Patients and family members are on average "Comfortable" with surgical residents and fellows performing any surgical step when the attending surgeon is present.
