This study aims to investigate that a single dose of tranexamic acid (TXA) will reduce blood loss and transfusion rates in elderly patients, undergoing intertrochanteric (IT) or femoral neck fractures surgery. Consecutive elderly patients receiving hip fracture surgery for stable or unstable IT fracture, treated with short intramedullary nail (IMN) insertion as well as cemented hemiarthroplasty for acute femoral neck (subcapital) hip fracture, were screened for inclusion in this single-centre randomized trial. Patients were randomly allocated to a study group by sealed envelope. One TXA dose of 15 mg/kg i.v. diluted in 100 ml N/S or one placebo dose i.v. in 100 ml N/S were administered 5 mins before the skin cut. Haemoglobin (Hb) concentration was measured at admission time and prior to surgery. Post-operatively it was measured on a daily basis until day 4, giving a total of four Hb measurements (days 1 to 4). The transfusion trigger point was determined in accordance with the French guidelines for erythrocyte blood transfusion. The transfusion trigger was 10 g/dl for patients at risk, while in all other cases, it was 9 g/dl. Information regarding the transfusions number was assessed directly by the hospital blood bank database. Blood loss was calculated by the Hb dilution method. Nadler's formula was used to calculate patients' blood volume. For calculation of total blood loss (TBL) expressed to total Hb loss and total Volume loss, the number of transfusions (55 grams of Hb per transfusion), the Hb concentration on preoperatively (Hgbi) and the Hb concentration on the last measure (Hgbe) were used. (Hb balance method). The primary efficacy outcome was the number of transfusions of allogeneic RBC from surgery up to day 4. The secondary ones were the total blood loss from surgery to day 4 as it was calculated by Hb-balance method. After randomization, 35 patients with femoral neck fracture and 30 patients with IT fracture received TXA prior to surgery. Respectively, 30 patients with femoral neck fracture and 55 with IT fracture didn't receive TXA. The groups did not differ significantly in their basic demographics (age, gender, BMI, injury mechanism, ASA score, co-morbidities). Results showed that patients undergoing hemiarthroplasty after receiving TXA, were transfused with less allogeneic RBC and had less total blood loss than patients that didn't receive TXA, but without statistical significance. While patients treated with IMN in the TXA group received a significantly lower number of RBC units than the control group (1.28 ± 1.049 vs 2.075 ± 1.685), (P = 0.0396), had a significantly lower loss of Hb (98.59 ± 55.24 vs 161.6 ± 141.7), (P = 0.0195) and a lower total blood volume loss (951.3 ± 598.9 ml vs 1513 ± 1247 ml), (P = 0.023). This trial confirmed TXA administration efficacy in reducing blood loss and transfusion rate in elderly patients undergoing hip fracture surgery. A TXA single dose may be a safer option, taking into account these patients' physiological status and co-morbidities.
To investigate the new theory of hydroneurolysis and hydrodissection in the treatment of carpal tunnel syndrome (CTS). Independently of the fluid hydrodissolution works due to mechanical forces and it may have some positive effects in patients with ischemic damage caused by scar tissue pressure at the nerve's surface. A prospective blind clinical study of 31 patients suffering from carpal tunnel syndrome, established by nerve conduction studies and clinical tests. 14 patients (out of 29), who refused to undergo an open operation as a treatment to their disease at this point of time, were treated with a simple ultrasound-guided injection at the proximal carpal tunnel. In order to exclude the biochemical influence of the fluid in the treating disease we choosed to infiltrate 3 cc. of normal saline 0,9%. In the follow-up period our group was asked to answer to a new Q-DASH score and visual analogue scale (VAS) 100/100 in 2, 4 and 8 weeks.Background
Methods
We compared ultrasound guided methylprednizolone-lidacaine infiltrations around inflammatory area of plantar aponeurosis with systematic use of NSAID'S. Also, we investigated the reliability of the sonographic criteria (a. swelling of aponeurosis more than 20% in comparison to the healthy foot, b. effusion around aponeurosis, c. calcium deposits) most used to identify plantar fasciitis in clinically suspicious patients. A prospective randomised controlled clinical trial, including 28 patients (mean age: 47 years, range: 36–65 years, 85% females) with typical clinical symptoms of plantar fasciitis. All of these patients undertook a soft tissue ultrasonography of the plantar aponeurosis, without Doppler. Then, we randomly divided our sample in 2 groups, group A (14 patients) and group B (14 patients). In group A patients we performed an ultrasound guided injection –in transverse view- around the swollen part of aponeurosis, while we managed group B patients with per os NSAID's treatment (meloxicam 15 mg, once per day) for 2 weeks.Introduction
Methods
To determine if double needle ultrasound-guided hydrodissolution and aspiration of intratendinous calcification is more effective treatment than blind subacromial corticosteroid injection. A prospective randomised comparative clinical study of 32 patients suffering from chronic symptomatic calcific tendinosis of the supraspinatous tendon. Group A (16 patients) received a double needle ultrasound-guided aspiration of the calcification, while group B (16 patients) underwent a blind subacromial betamethazone injection. As far as group A, we attached a syringe in the first needle, including 10cc. of normal saline (N/S), that we injected targeting the calcium deposit. Then we tried to achieve consecutive aspirations through the second needle.Background
Methods
We investigated whether grey scale early ultrasonography could be used for the accurate initial diagnosis of non displaced occult scaphoid fractures. This is a prospective blind clinical study that includes 36 patients that came to the emergency room with suspected clinical symptoms for scaphoid fracture but negative initial X-ray's. After that, a high resolution ultrasonography (without Doppler) was performed. Both wrists of each patient were examined, for comparison. After 14 days, new X-rays were performed, which compared to the early sonographic results of the patients.Introduction
