Background. Additional studies on clinical outcomes to determine the optimal time delay from injection of local anesthesia to skin incision for WALANT surgeries are needed. The authors aimed to propose the optimal time delay from local injection to skin incision for WALANT surgeries of the hand and wrist by analyzing intraoperative blood loss, postoperative pain scores, and complication rates. Methods. Thirty-four patients were consecutively recruited and allocated by either 7-min or 30-min delay for skin incision from local injection of epinephrine with lidocaine. Intraoperative bleeding and postoperative pain scores were analyzed between both groups by Mann–Whitney U-test, while complication rates were compared using Fisher’s exact test. Results. The present study did not find significant differences in mean intraoperative blood loss (8 ± 5.8 mL vs. 5 ± 2.2 mL, p=0.074), complication rates (18% vs. 0%, p=0.227), and mean pain scores (1.2 ± 0.5 vs. 1.4 ± 0.5, p=0.307) between the 7-min and 30-min groups. Conclusion. The authors conclude that a waiting time of 7 min from the injection of local anesthesia is sufficient to achieve comparable clinical outcomes for minor hand and wrist surgeries under WALANT.

Although still controversial, the use of diathermy instead of scalpel for skin incision and underlying tissue dissection is gradually gaining wide acceptance. This is due to the observation that no change in wound complication rates or postoperative pain are reported with the use of electrocautery. However, these studies include operations without the use of prosthetic materials during abdominal wall closure. The purpose of this study was to investigate the hypothesis that a) application of extreme heat may result in significant postoperative pain and poor wound healing because of excessive tissue damage and scarring respectively, and b) skin incision with the use of diathermy entails increased risk of wound infection in the presence of an underlying prosthetic material. One hundred twenty-five consecutive patients submitted to inguinal hernioplasty using the tension-free technique and fulfilling the inclusion criteria for the study were allocated alternately to either scalpel (n = 60), or diathermy (n = 57) groups. Eight patients had bilateral hernias. Five of them were allocated to the scalpel group and three to the diathermy group. According to the study protocol, they received both approaches for skin and underlying tissues incision, thus resulting in a total of 68 scalpel and 65 diathermy individual hernioplasties. Parameters measured included blood loss during the skin incision and underlying tissue dissection, postoperative pain and requirements for analgesics, the presence of wound dehiscence in the absence of infection, and postoperative wound infection on the day of discharge, on the day staples were removed, and 1 month after surgery. The two groups of patients were similar in relation to patient demographics, type of hernias, and operation details. Blood loss was minimal, and the amount of blood lost did not differ between the two groups. Diathermy group patients required less parenteral analgesics on the first postoperative day. A higher proportion of patients in the scalpel group continued to need oral analgesics on the second postoperative day compared to patients in the diathermy group. There was no difference between the two groups in terms of wound strength. Infectious complications were totally absent. The use of diathermy for skin incision during inguinal hernioplasty is as safe as the use of scalpel in terms of wound healing and reduces the analgesics requirements in the postoperative period.

Background Restrictive pulmonary dysfunction (RPD) is a risk factor for perioperative complications during gastrointestinal surgery. We hypothesized that high airway pressure due to RPD results in increased intraoperative blood loss during liver surgery. Thus, we investigated the effects of RPD on perioperative outcomes for liver resection. Methods This study included 496 patients who underwent curative liver resection at our hospital between April 2009 and April 2020. Perioperative outcomes for the RPD and control groups were compared. Restrictive pulmonary dysfunction was defined as % vital capacity <80%. Results Forty-one patients (8.3%) had RPD. No significant differences were observed in intraoperative blood losses (440 mL vs 320 mL, P = .340), overall complication rates (29.3% vs 31.2%, P = .797), or pulmonary complication rates (4.9% vs 9.0%, P = .286) between the RPD and control groups. In the 256 patients who underwent anatomical liver resection, 18 patients (7.0%) had RPD. The intraoperative blood loss was significantly higher in the RPD group (925 mL vs 456 mL, P = .013), but no differences in the overall complication rates (44.4% vs 37.3%, P = .528) or pulmonary complication rates (11.1% vs 10.5%, P = .589) between the two groups were detected. A multivariate analysis showed that RPD was an independent risk factor for intraoperative blood loss ≥500 mL during anatomical liver resection (odds ratio 4.132; 95% confidence interval 1.135-15.045; P = .031). Discussion Restrictive pulmonary dysfunction may be a risk factor for intraoperative blood loss during anatomical liver resection, which requires exposure of the main hepatic vein.

Background: Fear of poor wound healing have curtailed the use of diathermy for making skin incision. Scalpel produces little damage to surrounding tissue but causing more blood loss. Our aim of study was to compare electrocautery incision with scalpel incision in terms of incision time, blood loss, postoperative pain and wound infection.Methods: Total of 104 patients were included in the study undergoing midline abdominal surgery. Patients were randomized into electrocautery (group A) and scalpel (group B). The incision dimension, incision time and blood loss were noted intraoperatively. Postoperative pain was noted on postoperative day 2 using visual analog scale. Wound complications were recorded on every postoperative day till the patient was discharged.Results: 52 patients in each of the two groups were analyzed. There was significant difference found between group A and group B in terms of mean incision time per unit wound area, 8.16±1.59 s\cm2 and 11.02±1.72 s\cm2 respectively (p value=0.0001). The mean blood loss per unit wound area was found to be significantly lower in group A (0.31±0.04 ml\cm2) as compared to group B (1.21±0.21), p value=0.0001. There was no significant difference noted in terms of postoperative pain and wound infection between both groups.Conclusions: Electrocautery can be considered safe in making skin incision in midline laparotomy compared to scalpel incision with comparable postoperative pain and wound infection with less intraoperative blood loss and less time consuming.

Objectives: To compare the diathermy incision with scalpel incision in patients undergoing midline elective laparotomy. Design of Study: A prospective, experimental comparative study. Place and Duration: Department of surgery, PNS Shifa Karachi, from March 2007 to June 2008. Patients and Methods: A total of 100 patients were included in the study, and equally divided into 2 groups. Group A received scalpel incision while in group B diathermy was employed to incise all layers. Peroperative parameters including, incision time and blood loss were calculated. Postoperatively, pain was assessed by visual analogue score and wound infection documented. Results: Both groups included fifty patients each out of the total 44 females and 56 were males, with similar gender preposition in both the groups. Mean age of patients in scalpel group was 48.78 (±14.47) while it was 44.92 (±15.87) in diathermy group. The mean incision related blood loss in Scalpel group was 1.53 (±0.20) ml/cm2 and in Diathermy group was 1.43 (±0.20) ml/cm2, showing significantly less bleeding in diathermy group (p-value= 0.014). Diathermy group, with incision related time of 6.20 sec/cm2 (±0.97 sec/cm2), was significantly quicker (p-value= 0.003) than scalpel incision, with incision time of 6.76 sec/cm2 (±0.84 sec/cm2). Postoperative pain scores, recorded daily over five days, showed insignificant difference between the two groups. Conclusions: Diathermy, employed for midline laparotomy, is quicker and hemostatic, compared to the scalpel. The two are, however, similar in terms of wound infection and postoperative pain.

Currently, safety of laparoscopic pancreaticoduodenectomy (LPD) in patients with liver cirrhosis is unknown. The aim of this study was to explore postoperative morbidity and mortality and long-term outcomes of cirrhotic patients after LPD. The study was a one-center retrospective study comprising 353 patients who underwent LPD between October 2010 and December 2019. A total of 28 patients had liver cirrhosis and were paired with 56 non-cirrhotic counterparts through propensity score matching (PSM). Baseline data, intra-operative data, postoperative data, and survival data were collected. Postoperative morbidity was considered as primary outcome whereas postoperative mortality, surgical parameters (operative durations, intraoperative blood loss), and long-term overall survival were secondary outcomes. Cirrhotic patients showed postoperative complication rates of 82% compared with rates of patients in the control group (48%) (P = 0.003). Further, Clavien-Dindo ≥III complication rates of 14% and 11% (P = 0.634), Clavien-Dindo I-II complication rates of 68% and 38% (P = 0.009), hospital mortality of 4% and 2% (P = 0.613) were observed for cirrhotic patients and non-cirrhotic patients, respectively. In addition, an overall survival rate of 32 months and 34.5 months (P = 0.991), intraoperative blood loss of 300 (200–400) ml and 150 (100–250) ml (P<0.0001), drain amount of 2572.5 (1023.8–5275) ml and 1617.5 (907.5–2700) ml (P = 0.048) were observed in the cirrhotic group and control group, respectively. In conclusion, LPD is associated with increased risk of postoperative morbidity in patients with liver cirrhosis. However, the incidence of Clavien-Dindo ≥III complications and post-operative mortality showed no significant increase. In addition, liver cirrhosis showed no correlation with poor overall survival in patients who underwent LPD. These findings imply that liver cirrhosis patients can routinely be considered for LPD at high volume centers with rigorous selection and management.

Background: Anesthetic management of severe post burn neck contracture is difficult, demanding due to fixed flexion deformity of neck, incomplete oral occlusion and insufficient mouth opening leading to difficulty in intubation. Patients undergoing contracture release, skin graft harvest under general anesthesia (GA) were compared with patients undergoing the same surgery under tumescent local anesthesia (TLA) technique. Methodology: Twenty-one patients with post burn neck contracture undergoing contracture release with split skin grafting under GA were compared with twenty-one patients undergoing the same surgery under TLA. Post-operative pain and satisfaction were assessed using 10 cm VAS (Visual Analogue Scale).  Results: Demographic profile was comparable in both groups. Changes in intra-operative vital parameters remained insignificant. The average volume of tumescent solution used was 254.76 + 49.05ml. Blood loss was significantly decreased, postoperative pain relief was more than sixteen hours in thirteen patients and extended beyond twenty-four hours in six patients in the TLA group. Time for the first rescue analgesia was significantly lesser in the GA group and the average dose of injection tramadol used in the GA group was significantly higher within the first 24 h. Overall satisfaction in the TLA group was significantly higher than in the GA group. Conclusion: TLA can be used as sole technique for release of post burn neck contracture and harvest of split skin grafts with less blood loss and significantly better postoperative pain relief avoiding complications of general anesthesia.

Background and Hypothesis: Tranexamic acid (TXA) decreases blood loss in total knee arthroplasty (TKA). However, TXA evoked pain in rats by inhibiting GABA and glycine receptors in the spinal dorsal horn, and caused cellular death in ex vivo and in vitro human periarticular tissues exposed to clinical concentrations of TXA. We evaluated inpatient postoperative pain and blood loss in TKA performed with and without TXA. Project Methods: 105 consecutive cemented TKAs without TXA were compared to 72 consecutive cemented TKAs with TXA. Procedures were performed by a single surgeon using identical perioperative medical and pain-control protocols. Outcomes included: average of q2-4 hour pain scores during the first 24 hours after PACU discharge, average pain during remainder of stay, final pain score prior to discharge, time in minutes to first opioid after PACU discharge, total opioids in morphine equivalents (MEQs) during the first 24 hours after PACU discharge, average MEQs per remaining days of stay, and mean g/dL pre- to postoperative decrease in hemoglobin. Multivariate analyses accounted for 15 demographics and covariates. Results: The sex (p=0.393), age (p=0.784), and BMI (p=0.930) of the two cohorts were similar. Mean pain during the first 24 hours was greater (4.1 vs. 3.2, p=0.001), MEQs consumed during the first 24 hours were greater (45 vs. 37, p=0.069), and time to first opioid medication was shorter (326 vs. 414, p=0.023) in patients who received TXA. The decrease in hemoglobin was less in patients who received TXA (-2.2 vs. -2.7, p<0.001).   Conclusion and Potential Impact: Our hypothesis based on animal and laboratory studies that TXA may increase early postoperative pain was confirmed by three metrics. Consistent with the effective life of TXA, pain and opioid consumption after 24 hours did not differ based on TXA use. Further work is warranted to investigate the nature consequences associated with TXA, relative to its demonstrated benefits for blood conservation.

Objective: To investigate the effects of high tibial osteotomy (HTO) and total knee replacement (TKR) on postoperative pain of patients with knee arthritis. Methods: From February 2017 to March 2019, 72 patients with knee arthritis in our unit were collected for the experiment. Patients in the control group (CG, 35 cases) were treated with HTO, and research group (RG, 37 cases) were treated with TKR. Clinical efficacy. Visual Analogue Scale (VAS) score. Knee Society Score (KSS), and Hospital for Special Surgery (HSS) knee rating score of the two groups of patients were observed. Intraoperative blood loss, operative time and hospitalization expenses were observed, as well as the effect of knee joint recovery after operation. Results: In terms of overall effective rate, RG was superior to CG (p < 0.05). VAS score of RG was notably lower at 1 week and 2 weeks after operation than that in CG (p < 0.05). KSS of RG was evidently higher than that of CG (p < 0.05). HSS score of RG was notably higher than that of CG after operation (p < 0.05). The intraoperative blood loss and operative time in RG were notably better than those in CG (p < 0.05). The effects of knee joint recovery in RG was considerably better than that in CG (p < 0.05). Conclusion: TKR has a better clinical effect on elderly patients, which can reduce postoperative pain, intraoperative blood loss and operative time, and improve the recovery effect of knee joint.

Background: To compare outcomes of atraumatic hand surgeries using the WALANT technique versus intravenous regional anesthesia or local anesthesia with tourniquet. Methods: We conducted a comprehensive literature search using PubMed, MEDLINE, Embase, and Cochrane Library from inception to October 2018. All randomized or quasi-randomized trials and cohort studies comparing WALANT procedure versus local anesthesia or intravenous regional anesthesia with tourniquet among atraumatic hand surgeries were included. Methodological quality and risk of bias of eligible studies were assessed by three independent reviewers. The random effects model was used due to both statistical and clinical heterogeneity among studies. Results: The search yielded 496 records, of which 9 studies were included in the systematic review. We were able to pool findings for operative time, post-operative pain scores, patient satisfaction, and complication rates. On the average, the WALANT group had longer operative times by 2.06 minutes (pooled mean difference, random effects, 95% confidence interval 0.46 to 3.67 minutes, p = 0.01, I2 0%, p = 0.66). The post-operative pain scores were lower in the WALANT group by an average of two VAS points (random effects, pooled mean difference −2.40, 95% confidence interval −3.41 to −1.38, p < 0.00001; I2 0% p = 0.99). We had insufficient evidence to demonstrate a difference in terms of patient satisfaction (random effects, pooled risk ratio 0.98, 95% confidence interval 0.93 to 1.03, p = 0.36, I2 0%, p = 0.64) and complication rates (random effects, pooled risk ratio 0.40, 95% confidence interval 0.07 to 2.18, p = 0.29, I2 60% p = 0.08) between WALANT versus conventional methods. Conclusions: The WALANT group reported lower post-operative pain scores, but had slightly longer operative times. There are no significant differences between WALANT and conventional methods in terms of patient satisfaction and complication rates.
