Based on (2) and (3), the viable range of P d,f for dual-BESS long-duration operation can be stated as P_{d,f} in [begin{array}{*{20}c} { - P_{conv} - P_{D} } & {P_{conv} - P_{D} ]} end{array} (6).
Information on variables related to operative procedure (ie, duration of operation, type of operation, degree of wound contamination, surgeon, and antibiotic prophylaxis) was also reviewed.
The type of surgery, duration of operation, CPB and aortic clamping, and net fluid balance during the operation are recorded.
Disadvantages were concerns regarding environmental impact associated with ground testing and concerns about eventual cooling and condensation of some of the propellant on the spacecraft in long-duration operations.
Baseline assessment includes age, gender, body mass index, medical history and comorbidity, number of levels operated on, duration of operation, duration retractor placement, and use of cervical implants.
In the present study, PD was associated with a longer duration of operation, increased operative blood loss and longer postoperative hospital stay.
No significant differences were observed between groups in preterm delivery, birth weight, Apgar score, wound infection after surgery or duration of operation.
However, blood glucose levels in our study did not correlate with intra-operative blood loss, duration of operation or cold ischaemic times.
The incidence of hyperglycaemia had no relationship to pre-operative glucose levels, ischaemic time, duration of operation, donor weight or age.
