Randomised controlled trial of intramuscular tramadol versus transdermal buprenorphine patch for early postoperative surgical pain.

Background: This study assesses the efficiency of the buprenorphine patch system compared to the routine use of tramadol intramuscular injections in the context of the South African public healthcare sector.

Methods: Patients were randomised into two groups, who received routine tramadol injections 100 mg every 8 hours intramuscular and buprenorphine patches 5 mcg every hour. The study assessed the first 48 hours postoperatively.

[The physiological and hygienic bases of traffic control on high-speed transport].

The study of high-speed transport drivers' work has indicated that the latter is characterized by high nervous and emotional stress, the required long forced posture, high attention and monotonicity, as well as the physiologically power-intensive algorithm that places stringent requirements for the body's functional state. A combination of the above factors significantly deteriorates the drivers' ability to maintain the required level of vigilance, working capacity, and readiness for emergent actions, which requires the introduction of new security systems and the development of complex measures to minimize the influence of the above negative factors.

[Methods of nondrug prevention of diminished work capacity and impaired health in railway workers].

The paper deals with the physiological assessment of some biologically active food additives (BAFA). The authors formulate principles in selecting BAFA to prevent fatigability and premorbidity associated with safe railway traffic.

[Organization of a medical occupational rehabilitation system for locomotive team workers].

The paper deals with the setting up of a system for early diagnosis of premorbidity and for medical professional rehabilitation of locomotive teams. Non-drug preventive measures are shown to have a high rehabilitative effect.

[Problems in establishing special pensions for locomotive team workers].

The paper deals with a physiological rationale for fixing pensions for locomotive-drivers within the ranges of age and length of service. The study is based on the fact that the nature and conditions of their work accelerate their ageing and decrease their working capacity.
