The Effect of Intravenous Tranexamic Acid on Postoperative Ecchymoses after Upper Blepharoplasty.

Tranexamic acid has been increasingly used in facial plastic surgery to improve perioperative hemostasis. While subcutaneous tranexamic acid has been found to not significantly decrease postoperative ecchymoses following upper blepharoplasty, systemic administration has not previously been studied. A total of 325 patients undergoing upper blepharoplasty were randomly assigned to either receive intravenous tranexamic acid or serve as a control. Patients in the experimental group were administered 1 g of tranexamic acid intravenously 10 minutes before surgical incision. A similar upper blepharoplasty technique was performed by two American Society of Ophthalmic Plastic and Reconstructive Surgery-trained surgeons. Follow-up was conducted at a median of 8 days postsurgery. Patient photographs were evaluated by two independent graders to rate ecchymoses on a scale of 0 (least) to 10 (most). Of the 325 included patients, 138 patients received intravenous tranexamic acid and 187 patients did not. The average ecchymosis rating for the control group at day 8 was 5.8 ± 1.7, while the average rating for the tranexamic acid group at the same time point was 4.1 ± 1.6 (P < 0.0001). There was a trend toward decreased ecchymoses in the tranexamic acid group at earlier and later postoperative timepoints that did not reach statistical significance. No hemorrhagic or systemic embolic complications occurred. Systemic tranexamic acid may reduce postoperative ecchymoses after upper blepharoplasty surgery, reaching significance at the eighth postoperative day, which may lead to improved patient satisfaction and decreased occupational downtime.

Effectiveness of different doses of dexmedetomidine on intraoperative haemodynamic profiles and postoperative pain in patients undergoing abdominal surgery at Dilla University Referral Hospital, Ethiopia, 2024: a double-blind randomized controlled trial.

Abdominal surgery stands as one of the most frequently conducted procedures across surgical specialties, accounting for up to half of surgery-related expenses. Hemodynamic instability emerges as a significant concern during anaesthesia and surgery, provoked by the stress of intubation, surgical incision, and anaesthetic agents. Following abdominal surgery, pain is an inevitable consequence, typically managed with opioid-based analgesia. However, the adverse effects associated with opioids often overshadow their analgesic benefits, particularly in the context of abdominal surgery. Consequently, there exists a necessity to explore and assess alternative non-opioid pain management options post-abdominal surgery as part of a broader strategy to reduce opioid usage. The primary aim of this investigation is to assess the effectiveness of varying doses of dexmedetomidine in regulating intraoperative hemodynamics and alleviating postoperative pain in patients undergoing abdominal surgery. Ethical clearance and institutional review board were obtained from the ethical clearance committee of Dilla University College of Medicine and Health Sciences with protocol unique number of duirb/008/22-01. Our trial has been prospectively registered on the Pan African Clinical Trial Registry with a unique identification number for the registry PACTR202208813896934. Statistical package and analysis were performed by using SPSS version 25. The distribution of data was checked by using Shapiro-Wilk test and the homogeneity of variance was checked by Levene's test. Analysis of variance (ANOVA) and Kruskal-Wallis H test were used for normally distributed continuous data and non-normally distributed or non-parametric data, respectively. P value less than 0.05 with a power of 90% was considered statistically significant. There was a statistically significant increase in mean SBP in the control group at the different critical time points (P<0.05), as compared to the baseline value, while there was no significant difference in mean systolic blood pressure (SBP) between the baseline and all other levels for group 2 and group 3. A statistically significant increase in mean arterial pressure (MAP) was detected in the control group at immediately after intubation (P=0.009) as compared to the baseline value, while a statistically significant reduction in mean heart rate (HR) was observed in group 3 at 15th min after infusion and at 30th 30 min after induction compared to baseline with a P value of 0.002 and 0.008, respectively.Conclusion:Perioperative low-dose infusion of dexmedetomidine at the rate of 0.4mcg/kg/h is a useful anaesthesia adjuvant to control hemodynamic stress response to critical periods. It is wise to use this infusion dose as part of general anaesthesia to achieve better hemodynamic stability.

Pinch Grafts Versus Second Intention Wound Healing for Mohs Micrographic Surgery Defects Below the Knee: A Prospective Randomized Trial.

The surgical management of leg wounds following skin cancer extirpation is challenging. Pinch grafting (PG) is a technique that has been rarely described in the reconstruction of acute surgical wounds. The purpose of this study was to evaluate whether PG resulted in faster healing times for below the knee wounds following Mohs micrographic surgery (MMS) when compared with second intention healing (SIH). This was a prospective randomized trial of patients with post-Mohs micrographic surgical wounds of the lower extremity who were randomized either to receive pinch grafts or to heal by second intention. Patients were followed through a combination of in-person and virtual visits until their wounds were completely reepithelialized. Median time to wound healing was 36 days in the PG group versus 56 days for the SIH group, representing a 56% improvement in healing time. There were no differences in complications between the 2 groups with trends toward decreased rates of pain and infection in the PG group. PG is an effective simple method to hasten the healing of lower extremity wounds following MMS.

Effectiveness of Surgical Drains in Obese Patients Undergoing Lumbar Discectomy.

Background The placement of postoperative drains after spine surgery is a contentious issue, and its application has changed over time. Obesity itself is an independent risk factor for postoperative complications. Hematomas in the surgical wound are a complication that may necessitate revision surgery. Orthopaedic surgeons frequently use closed drainage in orthopaedic surgery to prevent the formation of a hematoma. It remains unclear whether drains reduce postoperative complications and improve clinical outcomes, especially in obese patients who are already at risk of such complications. Objectives To assess the incidence of surgical site infections (SSI) after lumbar discectomy in obese and morbidly obese patients with or without postoperative wound drainage and compare functional outcomes between both groups. Methodology A hospital-based retrospective study was conducted among 84 patients with obesity who underwent single-level lumbar discectomy at R. L. Jalappa Hospital and Research Centre, Kolar, India from May 2022 to April 2023. Drains were used for patients in Group A and avoided for patients in Group B. Results Postoperative C-reactive protein (CRP) levels in the non-drainage group were much higher than in the drainage group and were statistically significant. There was a statistically significant association found between body mass index (BMI) and postoperative SSI. In Group A, only three patients had SSI while in Group B, eight patients suffered from SSI. Conclusion Closed suction drains were shown to have a positive impact in reducing SSI in patients with obesity. Drain tip culture may be beneficial in detecting SSI at the earliest. Hence, we believe that closed suction drainage can be considered as a standard protocol in obese patients.

The use of incisional negative pressure wound therapy on high-risk breast cancer mastectomy patients

BackgroundThe main complications seen in patients who have undergone modified radical mastectomy (MRM) are seroma, surgical site infection, hematoma, wound dehiscence, flap necrosis, and nerve damage. While these complications lead to some problems the most feared effect in the early period is that they cause a delay in adjuvant treatment. Incisional Negative Pressure Wound Therapy (iNPWT) decreases wound dehiscence by reducing oedema and tension, especially in the incision line. This study aim to compare recovery times and wound site complications between patients treated with conventional wound dressings and patients treated with iNPWT after MRM. MethodsA retrospective screening was made of the data of 50 patients who underwent MRM because of breast cancer in the General Surgery Clinic of XXX Hospital between 2018 and 2022, and were at high-risk of wound site complications. Two groups were formed as 30 patients applied with iNPWT and 20 patients applied with conventional dressings. ResultsThe mean age of the 50 female patients was 53.58 years (range, 30–80 years). The most frequently seen complications were seroma (20 patients) and partial flap ischaemia (14 patients). The mean number of iNPWT applications was 1.30 (range, 1–2), and the mean number of days of application was 4.47 (range, 2–9). Postoperative seroma was observed in 8 patients in the iNPWT group and in 12 patients in the conventional dressings group (p = 0.018). Flap ischaemia and the probability of dehiscence was determined at a statistically significantly higher rate in the patients in the conventional dressings groups (p = 0.005, p = 0.021). ConclusionThe results of this study demonstrated that the use of iNPWT significantly reduced the amount of postoperative drainage, thereby contributing to early drain removal. Furthermore, iNPWT significantly reduced postoperative seroma, flap ischaemia, and flap dehiscence compared to conventional dressings.

Green Guidewire Combined with Epidural Needle-Saline Separating Minimize Invasiveness and Optimize Outcomes in Single-Port Laparoscopic Treatment for Pediatric Inguinal Hernia.

Objective: To investigate the application value, feasibility, and safety of modified single-port laparoscopic surgery in the treatment of pediatric inguinal hernia. Methods: One hundred and twenty cases of children with indirect inguinal hernia admitted from 2017 to 2022 were enrolled in the Control and Observation groups, with 80 and 40 cases, respectively. They underwent traditional open high ligation of the hernia sac and modified single-port laparoscopic high ligation of the hernia sac, respectively. The operation duration, surgical incision size, intraoperative bleeding, postoperative hospital stay, first ambulation time, and hospitalization expenses were compared between the two groups, as well as the incidence of surgical complications in the two groups. Results: The surgical incision size, intraoperative bleeding, postoperative hospital stay, and first ambulation time of the Observation group were less than those of the Control group. There was no significant difference in operation duration or hospitalization expenses between the two groups. Only two cases in the Observation group showed suture knot reactions after surgery, with no incision infection, inguinal hematoma, iatrogenic cryptorchidism, etc. The overall incidence of complications in the Observation group was lower than that of the Control group. Conclusion: Modified single-port laparoscopic surgery for inguinal hernia in children has the advantages of minimal invasiveness, and enhanced recovery, along with fewer complications and recurrence, hence it is worthy of recommendation in clinical practice.

Evaluation of Negative Pressure Dressings for Closed Surgical Incisions in Decreasing Surgical Site Infections After Emergency Laparotomy: A Randomized Controlled Study.

Objectives The aim of this study is to compare the effectiveness of negative pressure dressings (NPDs) versus conventional dressings for closed surgical incisions after emergency midline laparotomy, focusing on their impact on surgical site infection (SSI) rates, wound dehiscence, hospital stay duration, and cosmetic outcomes. Methods The randomized controlled study was conducted over 24 months, involving 80 patients aged 18-65 years who had peritonitis and underwent emergency midline laparotomies. Patients with diabetes mellitus, a BMI >35 kg/m², immunocompromised conditions, or those requiring re-exploration within 30 days of surgery were excluded. The participants were randomly assigned into two groups using a computer-generated randomization table: Group A, the case group, consisted of 40 patients who received NPDs, while Group B, the control group, included 40 patients who received conventional dressings. Data were recorded in Microsoft Excel (Microsoft Corporation, Redmond, WA, USA) and analyzed using IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, NY, USA), with a p-value of <0.05 considered statistically significant. Results The overall occurrence of SSIs within the 30-day follow-up period was significantly lower in the NPD group compared to the conventional dressing group (30% vs. 70%, p < 0.05). The mean duration of hospital stay was 14.85 ± 10.43 days for the NPD group and 15.4 ± 9.75 days for the control group, with no statistically significant difference (p = 0.712). The mean Vancouver Scar Scale score was 5.3 ± 2.47 in the NPD group and 6.5 ± 2.14 in the control group, also showing no statistically significant difference (p = 0.11). Conclusions NPDs significantly reduced the incidence of SSIs compared to conventional dressings, but they did not have a significant impact on scar cosmesis or the duration of hospital stay.

The prevention and management of complications in parotid and other ​ major salivary gland surgeries.

The prevention and management of complications that appear after the application of the classical techniques of traditional surgery of the major salivary glands, during the intra-operative or post-operative period, are not a common subject in the international literature and the number of scientific articles is relatively small. The most frequently occurring and most serious postoperative complications, early or late, are the partial or complete transection of the facial nerve or its branches, the development of neuroma on the transection of the greater auricular nerve, Frey’s syndrome, the deformed scars on the face, the numbness of the cheek and auricle, salivary fistula, sialocele, seroma, parotid removal skin intrusion and facial asymmetry, surgical incision keloid, and surgical wound inflammation-infiltration,which have been studied and adequately documented (30, 35). The increasingly frequently applied modern,advanced and minimally invasive-endoscopic surgical procedures which tend to replace traditional surgical techniques, are distinguished by their rapid recovery and significantly lower rate of complications. Endoscopic operations of the major salivary glands and the complica- tions associated with them are minor and usually belong to the general postoperative complications such as local inflammation, hematoma, injury, rupture and stricture of the excretory duct.

A single-centre RetrospeCtive sTudy Investigating patient-reported outcomeS of extended dressing wear time for incisional healing following orthopaedic surgery: the ARCTIS study.

Orthopaedic surgery is an effective intervention for treating the symptoms of degenerative joint disease or osteoarthritis (OA). Frequent wound dressing changes, unless clinically indicated, can disrupt the healing process and increase the occurrence of incision site contamination. Protection from contamination is critical for surgical incisions and, therefore, undisturbed wound healing (UWH) in surgical wound management is vital. This article describes a retrospective study reporting the clinical performance of a self-adherent, absorbent postoperative dressing, with a focus on dressing wear time. A single-centre, retrospective electronic medical record review of a convenience sample of adult patients treated with a dressing (Mepilex Border Post Op; Mölnlycke, Sweden) following elective hip or knee replacement was undertaken. Data relating to dressing wear time, rationale for dressing changes and patient-reported outcomes were extracted from a mobile health application moveUP Therapy (moveUP NV, Belgium). Health-related quality of life assessment was conducted using the EQ-5D-5L questionnaire and orthopaedic-specific quality of life (QoL) indicator tools. Of the 558 records reviewed, 151 respondents (27.1%) reported outcomes relating to dressing wear time and frequency of dressing change. The average wear time of the first dressing was 13.6 days (second dressing: 5.3 days). The proportion of patients who wore the first dressing for 1-7 days, 8-13 days and for ≥14 days was 17.2%, 13.2% and 69.5%, respectively. Data from the completed questionnaires revealed improvement in QoL over time. The results of this study are a good indicator of the suitability of the postoperative dressing for a 14-day wear time, in line with the principles of UWH.

A Review of Surgical Incisions Used for the Excision of Benign Parotid Tumors.

To provide surgical references for selecting appropriate parotidectomy incisions, reviewing modified approaches, incision designs, and associated complications. We have systematically searched 5 medical literature databases examining parotidectomy incision designs and postoperative complications from 2008 to 2021. There are a total of 9 novel incision designs: 1) posterior auricular hairline incision (PAHI); 2) combined preauricular and retroauricular incision (CPRI); 3) V-shaped incision (VI); 4) N-shaped incision (NI); 5) postaural incision (PI); 6) preauricular crutch incision (PCI); and 7) endaural incision (EI). Simultaneously, there are a total of 8 postoperative complications: 1) infection; 2) salivary fistula; 3) facial nerve palsy/paresis; 4) ear lobule numbness; 5) Frey syndrome; 6) facial deformity; 7) hematoma; and 8) tumor reoccurrence. Over the last decade, a surge in modified parotidectomy incisions has been witnessed in clinical practice. This expansion is attributed to rapid technical advancements and a deeper understanding of anatomy and histopathology. These modified approaches contribute significantly to improving cosmetic outcomes, minimizing associated complications, and enhancing patient satisfaction.

Therapeutic potential of cannabis for surgical wound healing in rats.

This study was conducted to evaluate the wound-healing activities of a Cannabis sativa L. plant extract and cannabidiol on incision wounds. An incision was created and sutured in rats under anaesthesia. Routine wound care procedures were applied for 10 days, followed by histological wound examinations. The cellular bioactivities of the hemp extract and CBD were assessed for MCP-1, EGF, BFGF, IL-8, and COL-1 using ELISA on the rat skin wound healing activity. A one-way ANOVA was used for the data analysis. The EGF values in the plasma were similar in the povidone-iodine, hemp seed oil, and hemp essential oil groups (P > 0.05). However, the EGF levels were lower in the CBD group compared to the other groups (P < 0.001, P < 0.005). The MCP-1 values in the hemp seed oil, hemp essential oil, and CBD were similar (P > 0.05), whereas povidone iodine exhibited lower MCP-1 levels compared to the other groups (P < 0.001, P < 0.005). It was determined that the plasma BFGF, IL-8, and COL 1 values of the groups were similar (P > 0.05). To our knowledge, this study is the first to evaluate the effects of CBD, seed oil, and hemp leaf extract on incision wound healing. It demonstrates that hemp extract holds greater potential benefits for wound healing compared to CBD.

Folliculectomy for the treatment of pre-ovulatory follicular stasis in three illegally captured West Coast green geckos (Naultinus tuberculatus) to enable wild rehabilitation

ABSTRACT Case history In 2023, the New Zealand Department of Conservation seized 63 endemic reptiles that were being held without a permit. This group included three adult female West Coast green geckos (Naultinus tuberculatus) that had been illegally removed from the wild 2 years earlier. They had been held in an outdoor enclosure with a pair of goldstripe geckos (Woodworthia chrysosiretica). Clinical findings On physical examination, all three geckos had at least two soft palpable masses in the coelom. Repeated ultrasonographic examination over several months confirmed the diagnosis of pre-ovulatory follicular stasis (POFS) in each gecko, and in subsequent weeks, more ovarian follicles developed in each animal. Laboratory findings All three geckos were negative on culture of cloacal swabs for Salmonella spp., and negative on PCR assay of a cloacal flush for Cryptosporidium spp., despite other reptiles in the seized group showing positive results for multiple Salmonella spp., and one other gecko being positive for Cryptosporidium parvum, subtype IIcA5G3. Treatment and outcome For all three geckos, para-midline ventral coeliotomy was performed under general anaesthesia, and folliculectomy of degenerate ovarian follicles was performed. Post-operative complications were seen in all three animals, which developed suture-line infections following disruption of normal skin shedding and entrapment of shed keratin in the surgical sites. A second surgery was undertaken to remove impacted keratin and caseous inflammatory material from the surgical wounds of all three animals and buried sutures were placed to close the coelomic wounds. The geckos were treated with 20 mg/kg ceftazidime IM every second day for 2 weeks post-operatively. Subsequent ecdysis (skin shedding) occurred without complication and the geckos were released back to the wild 10 months after admission. Clinical relevance The recommended treatment for POFS in reptiles is ovariectomy, which is not appropriate for wild animals. The use of folliculectomy to resolve preovulatory follicular stasis should be considered for animals where retaining reproductive ability is essential.

Contemporary outcomes after endoscopic vein harvesting for lower extremity bypass in a multicenter subspecialty practice

BackgroundEndoscopic vein harvesting (EVH) is considered the standard of care for coronary bypass procedures given the lower early morbidity from surgical wound complications. However, the use of EVH for lower extremity (LE) bypass remains controversial owing to concerns about decreased graft patency. In 2022, the BEST-CLI Trial (Best Endovascular vs. Best Surgical Therapy in Patients With Critical Limb Ischemia) demonstrated patients undergoing surgical bypass with adequate great saphenous vein quality experienced a lower incidence of major adverse limb events and mortality than those who underwent endovascular repair. Despite these results, wound complications from large harvest site incisions remain a significant barrier preventing surgical bypass as being the preferred initial treatment. To mitigate wound complications, our practice has adopted EVH as the standard approach for harvesting bypass conduit. Here, we report our recent 5-year experience using EVH for LE bypass. MethodsOne hundred sixty-eight LE bypasses with EVH were evaluated from 2017 to 2022. The cohort included 14 vascular surgeons in 8 hospitals. The primary end point was 30-day surgical wound complications. Secondary end points included bypass patency, need for major amputation, 30-day morbidity and mortality, length of operation, and length of hospitalization. Wound complications were measured using Szilagyi's method, with class I characterized by erythema necessitating antibiotics, class II having drainage or superficial dehiscence, and class III threatening graft integrity and requiring surgical intervention. ResultsA total of 168 LE bypasses with EVH were performed on 166 patients. Of these, 65.48% were male with a median age of 68.4 ± 9.7 years. There were no wound complications related to saphenectomy. Surgical site infections occurred in 22 patients (13.10%). Seven patients (4.17%) had class I complications, 12 (7.14%) had class II complications, and 3 (1.79%) had class III complications. Primary patency at 30 days was 96.10% and 86.84% at 1 year). Seven patients (4.17%) required major amputation at 30 days. The 1-year amputation-free survival was 89.39%. The 30-day postoperative stroke, myocardial infarction, and death rates were 0.60%, 0.60%, and 2.38%, respectively. The median operative time was 3.30 ± 1.18 hours. The median length of hospitalization was 3.00 ± 3.56 days. ConclusionsEVH minimizes saphenectomy wound complications without compromising patency and limb salvage rates. Older studies suggesting lower patency rates after EVH may have been limited by older technology and inexperienced operators. Whether EVH should be the standard of care for LE bypass warrants further investigation.

Efficacy and Safety of Magnesium Sulfate as an Adjunct to Ropivacaine Wound Infiltration in Thyroid Surgery: A Prospective, Double-Blind, Randomized Controlled Trial.

Background/Objective: Wound infiltration with local anesthetics emerges as a promising modality for postoperative pain alleviation. However, such strategies in neck surgery have not been a well-established practice. To assess wound infiltration with ropivacaine plus magnesium sulfate for pain relief following thyroid surgery. Methods: This prospective, double-blind, randomized study enrolled 68 patients who underwent thyroid surgery. Concerning the solution used for surgical wound infiltration, the study participants were randomly allocated into three groups: (1) 100 mg of ropivacaine (Group R); (2) 100 mg of ropivacaine plus magnesium sulfate 10 mg/kg (Group RMg); and (3) normal saline which served as a placebo (Group P). Pain perception both at rest and at movement, was measured using the Visual Analogue Scale (VAS) at 30 min, as well as at 1, 2, 4, 6, 12, and 24 h postoperatively. The total consumption of analgesics in morphine equivalents was also recorded. Moreover, adverse effects and patient satisfaction were recorded. Cortisol, TNF-α, and IL-6 levels were measured 30 min before infiltration and 6 h and 24 h postoperatively. Results: Demographics and clinical characteristics were similar between the groups. The VAS scores at rest and during movement were significantly lower in the RMg group compared to the saline or ropivacaine groups. Total analgesic consumption was also significantly lower in the RMg group. No operation-, wound-, or infiltration-related adverse effects were recorded in the study groups. Better overall satisfaction was obtained for the RMg group. Conclusions: Ropivacaine plus magnesium sulfate wound infiltration provided better pain control and the analgesic effect was more significant, contributing to effective postoperative analgesia in patients undergoing thyroid surgery.

Topical Tranexamic Acid on Donor Wounds in Burn Patients: A Randomized Placebo-controlled Trial.

Patients with major burn injuries are prone to massive blood loss owing to tangential excision of burn wounds and donor skin harvesting. In general, topical application of the antifibrinolytic drug tranexamic acid (TXA) to surgical wounds reduces bleeding; however, its effect on bleeding and re-epithelialization in superficial wounds of burns has not been explored. This study aimed to investigate the therapeutic potential of topical TXA in reducing blood loss and its effect on wound re-epithelialization in burn surgery. Split-thickness skin graft donor wounds in burn patients were paired and randomized to topical application of either TXA (25 mg/mL) or placebo. Endpoints were postoperative bleeding as measured by dressing weight gain per cm2 wound area, blood stain area per wound area, and visual evaluation of bleeding in the dressings. Healing time was recorded to analyze the effect on wound re-epithelialization. There was no significant difference in bleeding or time to re-epithelialization between the TXA and placebo wounds. A post hoc subanalysis of wounds with dressing weight gain above the median, showed a significant difference in favor of TXA. However, use of tumescence may have influenced end points. No significant adverse events related to the study drugs were observed. This study demonstrates that topical application of TXA (25 mg/mL) to split-thickness skin graft donor wounds does not delay re-epithelialization. Although a reduction in bleeding is suggested, further studies are needed to determine the role of topical TXA in reducing bleeding in burn surgery.

Impact of Wound Closure Technique on Surgical Site Infection After Lower Extremity Bypass Surgery

Surgical site infections (SSIs) are among the most common complications after lower extremity bypass (LEB). Both patient and hospital-related factors have been associated with SSI after LEB; however, the impact of surgical closure technique on SSI incidence remains unclear. Institutional electronic medical records (EMRs) were retrospectively queried for all LEB procedures performed from 2018 to 2022. Data were collected on patient demographics, medical comorbidities, operative details, wound closure techniques, and postoperative outcomes. Closure techniques included skin staples, absorbable monofilament (Monocryl), nonabsorbable monofilament (Nylon), or left open to heal by secondary intention. Logistic regression analysis was utilized to identify risk factors and calculate adjusted odds ratios (ORs) for postoperative SSI. A total of 517 patients underwent LEB surgery over the study period. SSI was diagnosed in 120 (23.2%) patients over a median follow-up period of 1.5years. The most common SSI locations were groin incision (40.0%), saphenectomy (31.7%), and leg incision (19.2%). The median onset of SSI was 18.5d (interquartile range [IQR] 11-28d) post-LEB surgery. Patients with SSI had higher body mass index (BMI) (28.2 [IQR 24.2-33.5] vs. 26.6 [23.1-31.5] kg/m2, P=0.03) compared with non-SSI patients. Patient age, sex, and medical comorbidities were otherwise similar between groups. There were no differences in closure technique (79.2% vs. 78.1% staples, 18.3% vs. 19.7% Monocryl, 0.8% vs. 1.8% Nylon, 1.7% vs. 0.5% open; P=0.53) in SSI versus non-SSI groups. On multivariate analysis, patient BMI (OR 1.04 per unit, 95% confidence interval [CI] 1.01-1.08, P=0.02), reoperative field (OR 1.81, 95% CI 1.00-3.25, P=0.03), and active smoking (OR 2.72, 95% CI 1.12-6.59, P=0.048) were independently associated with increased SSI incidence. Postoperative SSI resulted in prolonged hospital length of stay (LOS) (7 vs. 6days, P=0.04), unplanned hospital readmission (49.2% vs. 12.3%, P<0.001), and reoperation rates (64.7% vs. 8.1%, P<0.001). Bypass graft infection rates were also higher among patients suffering postoperative SSI (9.2% vs. 0.0%, P<0.001). On subset analysis of patients at increased risk of postoperative SSI, as found on multivariate modeling, there were no differences in closure technique between SSI and no SSI groups. This study provides insights on wound closure techniques and postoperative SSI made available through granular, operative data that are not found in large database analyses. Surgical wound closure technique was not associated with postoperative SSI after LEB surgery, even among patients at increased risk of infection. These data support individualization of wound closure techniques among patients undergoing LEB surgery.

Outpatient surgery for tibial plateau fractures.

The purpose of this study was to determine the rates of compartment syndrome and other early complications following outpatient open reduction and internal fixation (ORIF) of tibial plateau fractures. This was a retrospective cohort at a single US level I academic trauma centre of patients with tibial plateau fractures managed operatively. Inpatients received their definitive ORIF during their index hospital stay and were admitted post-operatively following ORIF. Outpatients were scheduled for ambulatory surgery during definitive ORIF. Exclusion criteria for outpatient surgery included compartment syndrome, polytrauma, open types IIIb/IIIc, and patients who received any internal fixation during index presentation. The primary outcome measure was post-operative compartment syndrome. Secondary outcomes were return to the 90-day return to the ED, 90-day readmission, surgical wound infection, thromboembolism, and 90-day mortality. An intention-to-treat (ITT) and as-treated (AT) analyses were performed. Totally, 71 inpatients and 47 outpatients were included. There were no cases of post-operative compartment syndrome. In the ITT analysis, there were no differences for inpatients vs outpatients for 90-day re-admission (22.5% vs 12.8%, p = 0.275), 90-day return to the ED (35.2% vs 17.0%, p = 0.052), infection (12.7% vs 2.1%, p = 0.094), DVT (7% vs 4.3%, p = 0.819), or PE 1.4% vs 0.0%, p = 1.000). The AT analysis showed a significantly higher 90-day re-admission (26.9% vs 2.5%, p = 0.003) and 90-day ED visit (38.5% vs 7.5%, p = 0.001) rate in the inpatient group. Appropriately selected patients with isolated tibial plateau fractures can have non-inferior rates of compartment syndrome and post-operative complications when compared to inpatients.

The Influence of Analgesic Wound Infiltration on Postoperative Pain and Inflammatory Cytokines in Open Colorectal Surgery: A Randomized Comparative Pilot Study.

Background and Objectives: Surgical wound analgesia has been analyzed in many studies, but few have focused on its relationship with inflammatory markers. As such, we aimed to determine the influence of analgesic surgical wound infiltration in open colorectal surgery on the seric levels of pro- and anti-inflammatory markers and the associated efficacy in postoperative pain control. Materials and Methods: Forty patients who underwent open colorectal surgery were prospectively randomized: group 0, epidural analgesia; group 1, intravenous analgesia (control), group 2, preincision and prelaparoraphy infiltration; and, group 3, prelaparoraphy infiltration. Wound infiltration was performed with ropivacaine. We analyzed the levels of IL-6 and IL-10 cytokines before and 6 h after surgery and their correlation with pain scores. Results: The postoperative Il-6 levels were significantly lower in group 0 than in the control (p = 0.041). The postoperative Il-10 levels were significantly higher in group 3 (p = 0.029) than in the control. Six hours after the operation, the pain scores were significantly lower in all groups than in the control (p = 0.005, p = 0.022, and p = 0.017 for groups 0, 2, and 3, respectively). Pain scores were significantly correlated with Il-10 levels in group 2 (p = 0.047); in group 3, IL-10 levels directly correlated with those of Il-6 (p = 0.026). Conclusions: The analgetic effect of preincisional and prelaparoraphy analgetic infiltration was efficient. The analgetic infiltration of the surgical wound prior to closure stimulates both the inflammatory activator and regulator interleukins.

The hidden pandemic: surgical wound complications and the use of technology for early detection and prevention

The global volume of surgery is considerable and growing. It was estimated that 312.9 million surgical procedures were performed in 2012, which represented a 33.6% increase over 8 years. Despite advances in surgical technique, infection control practices and wound care, surgical wound complications such as surgical site infection and surgical wound dehiscence are unwanted outcome following surgery.

Case Report: Multidisciplinary management of severe blast-related craniofacial and ocular injuries at artisanal gold mining sites in Niger: An unusual case report and comprehensive literature review

Blast-related craniofacial and ocular injuries have traditionally been associated with battlefields. In civilian populations, these injuries were infrequent, primarily arising from accidental explosions or terrorism incidents. Explosions can inflict severe damage to the neurological, ocular, and auditory systems through blast waves, high-velocity foreign bodies, and thermal radiation. The pathophysiology of blast-related craniofacial injuries is specific and complex, with severe cases often involving both penetrating and blunt trauma, leading to high mortality and morbidity rates. These injuries necessitate multidisciplinary management and can be defined as intracranial polytrauma. Recently, Niger has seen a surge in blast injuries, predominantly due to the increase in clandestine artisanal gold mining. Managing these injuries in resource-limited settings poses significant challenge. Comprehensive national data on these injuries are sparse due to high pre-hospital mortality rates and their infrequent occurrence, resulting in limited experience among our local physicians in their management. We present a rare case involving an artisanal gold miner with a history of smoking and previous concussions from explosion exposures. The patient was transferred to our hospital following severe craniofacial and ocular injuries caused by an accidental dynamite explosion at a mining site. On admission, the patient presented altered consciousness, agitation, unstable vital signs, multiple craniofacial wounds, including a large frontal wound with brain substance extrusion, diffuse facial burns, left globe rupture, and rhinorrhagia. After resuscitation and stabilization, brain imaging revealed multiple complex craniofacial fractures with foreign bodies. The patient underwent multidisciplinary surgical management. However, the postoperative course was complicated by post-concussive syndrome, and infection of the surgical wounds, necessitating surgical revision. Following the second surgery, the postoperative course was uneventful, although the patient experienced reduced visual acuity. This case highlights the management challenges in Niger and underscores the urgent need for clinical studies and training for gold miners to enhance safety practices in their activities.
