Complications of Minor Cutaneous Surgery in Patients Under Anticoagulant Treatment

Anticoagulant use is common in the elderly population. The role of these medications in the postoperative period is not well defined. We designed a prospective study to evaluate the incidence of postoperative complications in patients taking aspirin and warfarin. A prospective study was performed on 102 patients undergoing minor cutaneous plastic surgery. The number of subjects using regular aspirin, warfarin, and that of the patients with no anticoagulant medication were 37, 21, and 44, respectively. Complications were defined as minor, moderate, or major based on predetermined criteries. Of patients taking warfarin, 57% had some complication, significantly more than complications in the control group. The number of major complications in the warfarin group was significantly higher than those of the control and aspirin groups (p = 0.02). Also, the total number of complications in the warfarin group was significantly higher than the control group, but there was no significant difference between aspirin and control groups (p > 0.05). Cutaneous surgery in patients who receive warfarin is associated with a risk of major complication, but this risk does not exist in the patients receiving chronic aspirin treatment.

The postoperative analgesic effect of tramadol when used as subcutaneous local anesthetic.

Recently, it has been shown that tramadol was an effective local anesthetic in minor surgery. In this study, its efficacy for relieving postoperative pain was evaluated. Forty patients undergoing minor surgery (lipoma excision and scar revision) under local anesthesia were included. The patients were randomly allocated into two groups: In group T (n = 20), 2 mg/kg tramadol, and in group L (n = 20), 1 mg/kg lidocaine were given subcutaneously. In both groups, the injection volume was 5 mL containing 1/200,000 adrenalin. The degree of the erythema, burning sensation, and pain at the injection site were recorded. Incision response, which is a degree of the pain sensation during incision, was recorded and graded with the visual analog scale (VAS) 0–10. After incision, VAS values were recorded at 15-min intervals. When the VAS score of the pain during surgery exceeded 4, an additional 0.5 mg/kg of the study drug was injected and this dosage was added to the total amount. Patients were discharged on the same day. Subjects with VAS ≥4 were advised to take paracetamol as needed. No side effects were recorded in either group except for 1 patient complaining of nausea in group T at the 30th min of operation. After 24 h, patients were called and the time of first analgesic use and total analgesic dose taken during the postoperative period were recorded. During the 24 postoperative hours, 18 of 20 (90%) subjects did not need any type of analgesia in group T, whereas this number was 10 (50%) in group L (P < 0.05). The time span before taking first analgesic medication was longer (4.9 ± 0.3 h) in group T than that of group L (4.4 ± 0.7 h) (P < 0.05). We propose that tramadol can be used as an alternative drug to lidocaine for minor surgeries because of its ability to decrease the demand for postoperative analgesia.

Effect of steroids on edema, ecchymosis, and intraoperative bleeding in rhinoplasty

A double-blind, randomized study was designed to determine the efficacy of dexamethasone in decreasing periorbital edema and ecchymosis after rhinoplasty. Sixty rhinoplasty patients undergoing hump resection and lateral osteotomy were included in the study and were divided into 6 groups: group 1 (n = 10), single dose of 8 mg intravenous (IV) dexamethasone 1 hour before the operation; group 2 (n = 10), single dose of 8 mg IV dexamethasone at the beginning of the operation; group 3 (n = 10), 3 doses of 8 mg IV dexamethasone 1 hour before the operation, and 24 and 48 hours after the operation; group 4 (n = 10), 3 doses of 8 mg IV dexamethasone at the beginning of the operation, and 24 and 48 hour after the operation; group 5 (n = 10), 3 doses of 8 mg IV dexamethasone immediately after the operation, and 24 and 48 hours after the operation; group 6 (n = 10), control, no dexamethasone administration before or after the operation. Intraoperative blood loss was recorded for each patient. Patients were evaluated at 24 hours and days 2, 5, 7, and 10. For the postoperative evaluation of periorbital ecchymosis and edema, a scale of 0 to 4 points was used. There was no significant difference between groups in terms of bleeding (P > 0.05). In the groups using steroid before osteotomy, edema and ecchymosis were significantly lower during the first 2 days compared with the control group (P < 0.05). No significant difference was seen between groups 1 and 2. When patients were evaluated on day 5, edema and ecchymosis were significantly lower in groups 3 and 4 (P < 0.05) compared with other groups, but there was no difference between them. Group 5 had a significantly higher level of edema and ecchymosis compared with groups 1 through 4 at 24 hours and at days 2, 5, and 7 (P > 0.05). There was no significant difference between groups on day 10. In conclusion, if the first dose is given before osteotomy, triple-dose steroid application is the best bet for decreasing postoperative edema and ecchymosis. None of the patients had any complications related to the use of dexamethasone.

Fournier's Gangrene: Overview of Prognostic Factors and Definition of New Prognostic Parameter

OBJECTIVES To identify the prognostic factors and the new parameters that might predict a worse outcome in nonsurvivors compared with survivors of Fourniers gangrene (FG) and evaluated the validity of the Fourniers Gangrene Severity Index (FGSI) in patients with FG. METHODS The medical records of 18 patients with FG who were treated and followed up in our clinic were reviewed. Data were collected in terms of medical history, symptoms, and physical examination findings. The biochemical, hematologic, and bacteriologic study (aerobic and anaeorobic wound cultures) results at admission and at the final evaluation, the physical examination findings, the timing and extent of surgical debridement, and the antibiotic therapy were also recorded. The Charlson Comorbidity Index (CCI) and FGSI were evaluated stratified by survival. RESULTS The results were evaluated for 2 groups: those who survived (n = 14) and those who did not (n = 4). The admission FGSI score was 5.00 +/- 2.91 (range 0-10) for survivors compared with 13.5 +/- 2.62 (range 9-15) for nonsurvivors (P = .001). The CCI score was 3 +/- 1.5 in survivors and 7 +/- 2.2 in nonsurvivors (P = .008). Individual laboratory parameters such as hypomagnesemia, hemoglobin, hematocrit, alkaline phosphatase, creatinine, and the heart and respiratory rates were associated with a worse prognosis. In addition, a FGSI >9, rectal involvement, colostomy diversion, and a high CCI were associated with high mortality. CONCLUSIONS Low magnesium levels might be a new parameter for a worse prognosis. High CCI and FGSI scores might be associated with a worse prognosis in patients with FG. A FGSI threshold of 9 was a predictor of mortality during the initial assessment.

Dual preconditioning: effects of pharmacological plus ischemic preconditioning on skin flap survival.

To enhance skin flap viability, pharmacological and ischemic preconditioning methods were investigated intensively. This study was designed to determine whether combined local dexamethasone administration and pedicle clamping would result in an additive enhancement of skin flap survival in the rat model. Twenty-eight male Sprague–Dawley rats were included in dexamethasone injection, clamping, clamping plus dexamethasone injection, and control groups. A rectangular random skin flap (3 × 11 cm) was outlined as bipedicled on the back of the animals. The dexamethasone or saline injection points in the flap were standardized. In the dexamethasone injection group, after raising the flaps, a total of 2.5 mg/kg dexamethasone was injected into the flaps. In the ischemic preconditioning group, 1 hour after saline injection, the cranial pedicle was clamped for 20 minutes and then 40 minutes reperfusion was performed. The clamping-plus-dexamethasone injection group was the same as the clamping group except dexamethasone was injected instead of the saline. In the control group, saline was injected instead of dexamethasone. Regardless of the group, all flaps were cut at the cranial side at the end of the 2 hours and were sutured back. On day 7, the surviving area was significantly greater in all experimental groups compared with the control group (p < 0.05). Furthermore, the clamping-plus-dexamethasone group demonstrated the highest flap viability.

Relaxation incision and fascia lata grafting in the surgical correction of penile curvature in Peyronie's disease.

The purpose of this study was to evaluate the effects of treatment of curvature in Peyronie’s disease with a relaxation incision and fascia lata grafting. Between 2000 and 2002, this technique was used for 12 patients with a 1-year history of plaque and curvature of more than 35 degrees. Penile degloving was performed with a circumferential incision. The tunica defect was closed with fascia lata grafting after a relaxation incision. For all patients, penile curvature was corrected and normal erections were achieved. No complication was observed in 9 to 24 months (mean, 10 months) of follow-up monitoring. The initial results suggested that tunica albuginea incision and fascia lata grafting could represent an alternative for the treatment of curvature in Peyronie’s disease. Further studies are warranted.

Comparison of Local Anesthetic Effects of Tramadol With Prilocaine During Circumcision Procedure

OBJECTIVES To compare the local anesthetic effects of tramadol hydrochloride with prilocaine for circumcision procedure. METHODS This study included 40 patients with American Surgical Association-I scores. Patients were randomly allocated to receive either 5% tramadol (2 mg/kg) plus adrenaline (0.0125/mL) (group 1, n = 20) or 2% prilocaine plus adrenaline (0.0125/mL) (group 2, n = 20). The degree of burning sensation and pain at the injection site were documented. Sensory block was assessed 1 minute after injection and the patients were asked to grade touch and pinprick sensation. Five minutes after drug administration, incision was performed and intensity of pain, felt by the patient was evaluated on a 4-point scale (0-3). Pain at the injection site and local skin reactions were also recorded. RESULTS Mean ages were 9.7 and 10.3 years for groups 1 and 2, respectively. Mean duration of surgery was 19.6 minutes. In control visit, 2 of 20 (10%) in group 1 and 10 of 20 (50%) children in group 2 reported extra need for oral ibuprofen (P <.05). First analgesic medication time was 9.5 (+/- 2.1) hours in group 1 and 8.7 (+/- 3.1) hours in group 2 (P >.05). Total postoperative ibuprofen consumptions were 10 and 50 mg for groups 1 and 2, respectively (P <.05). CONCLUSIONS A combination of tramadol 5% plus adrenaline can provide a safe and effective local anesthesia during circumcision procedure and postoperative period in children.

Dual synergistic effect: the effect of dexamethasone plus carnitine on skin flap survival.

Dexamethasone has well-known useful effects in dealing with the progression of necrosis. Carnitine is an endogenous cofactor, for having a regulatory action on the energy flow from different oxidative sources. The aim of this study was to determine whether combined local dexamethasone and systemic carnitine administration would result in an additive enhancement of skin flap survival in the rat model. A rectangular (3 cm × 11 cm) dorsal random skin flap was elevated on the rats and then sutured back into its original site with separate sutures. Overall, 40 rats were allocated randomly into 4 groups: Group 1 (control group, n = 10), group 2 (Dexamethasone group, n = 10, 2.5 mg/kg), group 3 (carnitine group, n = 10, 100 mg/kg), group 4 (dexamethasone plus carnitine group, n = 10). The mean flap survival area was 57.50 ± 5.2% (mean survival area ± SD) in control group (group 1), 71.5 ± 4.8% in the dexamethasone group (group 2), 73.0 ± 5.5% in the carnitine group (group 3), 85.30 ± 6.1% in the dexamethasone plus carnitine group (group 4). In conclusion, based on the findings of this experimental study, the synergistic effect of carnitine and dexamethasone on skin flap viability is determined.

Effect of Cerebrospinal Fluid Leakage on Wound Healing in Flap Surgery: Histological Evaluation

The aim of this study was to find out the effect of CSF leakage on wound healing after flap surgery. Sixteen male Wistar rats were used. The superiorly based rectangular dorsal skin flap 3 × 3 cm was elevated at the interscapular region. Through this opening, paraspinal muscle dissection and three-level bilateral laminectomy were done. Finally, a dura defect with a diameter of 3–4 mm was created. In the control group, laminectomy was performed as in the study group but the dura was left intact. Persistent CSF leakage was confirmed using isotope cisternography. At the end of 2-week study period, there was no necrosis, infection, or dehiscence of the flap in either group. On necroscopy, cyst formation over the dura defect was detected in 4 animals of the study group. Another gross finding in this group was intensive vascularization of the undersurface of the flap and wound bed. With HE staining, the tissue sections from the study group revealed new vessel formation with small diameter, increase in the reactional mesenchymal tissue, granulation tissue, degeneration of the striated muscle fibers, dystrophic calcifications, fat necrosis, and coagulation necrosis (ischemic necrosis). In the control group, there was only minimal lymphocytic invasion of the subdermal plane. In this study, we have shown that CSF leakage itself has effects on wound healing in the absence of known causative factors.

The Value of Scintimammography in Reduction Mammaplasties: A Preliminary Study

Reduction mammaplasty results in architectural distortion, fat necrosis, and heavy scarring of the breast. In such conditions, mammography (MG) might not be reliable and an alternative unfailing imaging technique is demanded to prevent unnecessary apprehension and biopsy. With this study, the value of Tc-99m sestamibi (MIBI) scintimammography (SCM) as an adjunct test after reduction mammaplasty was explored. MIBI scintigraphy is not affected by scar tissue or breast density and is able to differentiate benign and malignant lesions. The study was conducted on 12 women undergoing a reduction mammaplasty operation (McKissock technique). The average age was 38 and the average weight of breast tissue removed from each breast was 320 g. All patients, except one who was 21 years old, underwent MG and SCM preoperatively, and these tests were repeated at the sixth postoperative month. Preoperative MG and SCM revealed no pathology except a finding in one patient consistent with fibroadenoma. Postoperatively, the most common findings in MG were parenchymal redistribution, elevation of the nipple, and retroareolar fibrotic bands. Calcifications and oil cysts were not seen. Other findings were areola and skin thickening. Interestingly, these findings were not evident on the SCM, in fact it was not possible to state whether or not the breast had been operated on. In conclusion, SCM may not be used as screening test, but it should be considered when the postoperative MG is not informative or is complicated by scaring. In this condition, SCM may be used as a complementary method to MG and may help to prevent unnecessary breast biopsies.
