    • BACKGROUND: Functional characteristics of the pharynx and upper esophagus, including aspiration episodes, were investigated in 14 awake volunteers during various levels of partial neuromuscular block. Pharyngeal function was evaluated using videoradiography and computerized pharyngeal manometry during contrast bolus swallowing. METHODS: Measurements of pharyngeal constrictor muscle function (contraction amplitude, duration, and slope), upper esophageal sphincter muscle resting tone, muscle coordination, bolus transit time, and aspiration under fluoroscopic control (laryngeal or tracheal penetration) were made before (control measurements) and during a vecuronium-induced partial neuromuscular paralysis, at fixed intervals of mechanical adductor pollicis muscle train-of-four (TOF) fade; that is, at TOF ratios of 0.60, 0.70, 0.80, and after recovery to a TOF ratio > 0.90. RESULTS: Six volunteers aspirated (laryngeal penetration) at a TOF ratio < 0.90. None of them aspirated at a TOF ratio > 0.90 or during control recording. Pharyngeal constrictor muscle function was not affected at any level of paralysis. The upper esophageal sphincter resting tone was significantly reduced at TOF ratios of 0.60, 0.70, and 0.80 (P < 0.05). This was associated with reduced muscle coordination and shortened bolus transit time at a TOF ratio of 0.60. CONCLUSIONS: Vecuronium-induced partial paralysis cause pharyngeal dysfunction and increased risk for aspiration at mechanical adductor pollicis TOF ratios < 0.90. Pharyngeal function is not normalized until an adductor pollicis TOF ratio of > 0.90 is reached. The upper esophageal sphincter muscle is more sensitive to vecuronium than is the pharyngeal constrictor muscle.

  • Subcontract Coordination in Construction
  • 1998
  • Ingår i: International Journal of Production Economics. - 0925-5273 .- 1873-7579. ; 56-57, s. 503-509

    • The building industry in Sweden has for the last five years been under hard pressure to reduce costs, and lead times, while at the same time improving quality. During this period the range of services such as air distribution, heating, cooling and electrical systems has continued to increase, creating more complex buildings. Today, we encounter problems with communication, boundaries between subcontractors, too many people in the same place at the wrong time and too little emphasis on the testing phase. In order to meet customer's expectations, to have a fully functional and tested product at a given time, several main contractors in Sweden have started to use a special subcontract coordinator in an effort to reduce problems.The case study method was used to find out how the subcontract coordinator was working, where in the organisation he should be placed and what he adds to the construction process. Studies have been conducted on several types of building projects, varying organisations and geographically spread projects.The need for the subcontract coordinator is clearly stated among all types of participants. The function adds a more holistic outlook in scheduling, communication, troubleshooting and performance testing before project completion. The aim of this study is to provide a guideline for the coordinator's work. The results can be used to achieve a smoother construction phase with a successful project close-out.
