摘要Objective:
To evaluate the negative pressures generated by commonly used subgaleal drains in neurosurgical practice and to analyse the effects of human factors on the pressures generated.

Methods:
The negative pressures generated by two different subgaleal drains, namely the Jackson-Pratt® drain (Cardinal Health), and the Exudrain® (Wellspect HealthCare) were measured by pressure sensors. Patients were asked to generate negative pressures by squeezing the reservoirs under standardised instructions, followed by natural expansion of the reservoirs. Two measurements were done for both dominant and non-dominant hands, and for each drain.

Results:
Twelve patients were recruited from July 2019 to November 2019. The mean pressure range and mean maximal negative pressure were significantly higher for men than for women (P<0.005). When comparing between medical and non-medical staff, drain designs, and hand dominance, there were no significant differences in the mean pressure range and mean maximal negative pressure generated.

Conclusion:
Sex was the only human factor that significantly affected the negative pressures generated by the tested subgaleal drains, irrespective of drain design. In addition, the mean maximal pressure generated by our recruited subjects exceeded the tested subgaleal drain specification of the manufacturer (75 mm Hg). Caution should be advised when applying pressure.
