  • Silicone ring tourniquet or Pneumatic Cuff tourniquet for total knee arthroplasty
    International orthopaedics, 2016
    Co-Authors: Jean-yves Jenny, David Bahlau, Sandra Wisniewski
    Abstract:

    The goal of the present study was to evaluate the potential advantages of a silicon ring tourniquet in comparison to the conventional Pneumatic Cuff tourniquet. The tested hypothesis was that the calculated blood loss will be decreased after use of the silicone ring tourniquet. The study was monocentric and mixed retrospective and prospective evaluation of prospectively collected data. Inclusion criterion was implantation of a total knee arthroplasty. The retrospective control group involved 39 patients operated on with a Pneumatic Cuff tourniquet. The prospective study group involved 33 patients operated on with a silicone ring tourniquet. All patients were followed for three months. Primary criterion was the calculated blood loss (OSTHEO formula). Secondary criteria were pain on third post-op day, need for allogenic transfusion, haemoglobin drop, delay of discharge, and occurrence of complications. The mean calculated blood loss was 901 ml in the study group and 989 ml in the control group (NS). There was no significant difference in pain evaluation and haemoglobin drop between the two groups. There was a non significant decrease of allogeneic transfusion and length of stay in the study group. There was a significant decrease of complication rate in the study group, and especially for skin complications. The tested hypothesis was not confirmed: there was no significant change in the calculated blood loss. No bias was identified in complication analysis. The decreased rate of skin complication might be a positive influence of the silicone ring tourniquet.

  • silicone ring tourniquet versus Pneumatic Cuff tourniquet in carpal tunnel release a randomized comparative study
    Journal of Orthopaedics and Traumatology, 2013
    Co-Authors: Georgios I Drosos, Nikolaos I Stavropoulos, Grigorios Tripsianis, Athanasios Ververidis, Rodion Mavropoulos, Konstantinos Kazakos
    Abstract:

    The aim of the present study was to compare the pain levels resulting from the use of a silicone ring tourniquet (SRT) to those resulting from the use of a classic Pneumatic Cuff tourniquet (PT) in patients undergoing carpal tunnel release under local anesthesia. Fifty patients that underwent carpal tunnel release under local anesthesia were randomized using the technique of stratified randomization by minimization. A forearm tourniquet was applied: a standard PT was used in 25 patients, and an SRT was used in the other 25 patients (the model of SRT used was selected according to the standard systolic blood pressure). Patient demographics and complications were recorded. Pain levels were assessed with the visual analogue scale and were recorded (a) just after tourniquet application, (b) 5 min after tourniquet application, and (c) just before tourniquet removal. There was no statistical significant difference in patient demographics between the two groups. The mean tourniquet time was similar for both groups (p = 1.000). The difference between the mean final pain level and the mean initial pain level was statistically significant for the SRT group (p = 0.010) and highly statistically significant for the PT group (p < 0.001). The mean final pain level for the PT group was higher than that for the SRT group (p = 0.043). According to the findings of this study, in patients who underwent carpal tunnel release under local anesthesia, the pain levels at the end of the operation and those just before the removal of the tourniquet were higher in the PT group than in the SRT group of patients.

  • silicone ring versus Pneumatic Cuff tourniquet a comparative quantitative study in healthy individuals
    Archives of Orthopaedic and Trauma Surgery, 2011
    Co-Authors: Georgios I Drosos, Nikolaos I Stavropoulos, Konstantinos Kazakos, Grigorios Tripsianis, Athanasios Ververidis, Dionisiosalexandros Verettas
    Abstract:

    Introduction The aim of the present study was to compare a new silicone ring tourniquet (SRT) with a classic Pneumatic Cuff tourniquet (PT) in terms of tolerance and recovery time following their use in healthy volunteers.
