The use of a PID controller to model vecuronium pharmacokinetics and pharmacodynamics during liver transplantation

Abstract: A four-phase proportional-integral-derivative (PID) controller was evaluated under the extremely unstable conditions of liver transplantation. Vecuronium was delivered to achieve 80%-90% neuromuscular blockade as measured by electromyogram (EMG). The first two controller phases delivered boluses and a constant infusion calculated to rapidly achieve setpoint, followed by a proportional-derivative (PD) phase at 35% from setpoint, and PID within 10% of the setpoint. During liver transplantation, the sources of sy… Show more

“…Compared with previous researchers' results, the mean of the mean T1% and error in automatic control is 9.52 and 0.48, respectively. Except Derene's [8], the other results of mean of mean T1% error are between 0.19 to 1.3 after taking absolute calculation. The best results were presented by Shieh et al [3] who used rocuronium with hierarchical rule-based FLC.…”

“…shows a comparison of published human clinical results obtained with different drugs with an EMG monitor. General speaking, these studies [3][4][5][6][7][8][9][10][11][12] can be clustered into different types of anesthetic medicines, such as atracurium, rocuronium, vecuronium, and pacuronium. Regarding control by rocuronium, Shieh et al [3] presented the controlling combination of rocuronium with hierarchical rule-based FLC.…”

“…We use a biophysically-reasonable simulation study including models of DBS, Vim, motor cortex, motor neurons in the spinal cord, and muscle fibers to generate muscle activities (represented by EMG). To link Vim-DBS to EMG signals in our model-based control framework, model-predicted EMG signals, generated by our simulation study, are used to calculate the feedback biomarker by a polynomial fit, which is processed and implemented in a proportional-integral-derivative (PID) controller [34][35][36] that automatically updates the appropriate DBS frequency. Our model-predicted EMG can replicate the essential tremor symptoms during DBS-OFF, and is consistent with clinical observations of tremor during different frequencies of Vim-DBS.…”

“…Recent developments in the field of closed-loop drug delivey either employ the classical PID (proportionalintegral-differential) controller [OHD+97], use a modelbased (pharmacodynamic/pharmacokinetic model, PKPD) [OSA9 1 J or a rule-based approach (fuzzy logic) [MLER97].…”
