Ideal Drainage Output of Post-operative Neck Suction Drain

Not Applicable

Withdrawn

• Conditions: Head and Neck Neoplasms; Neck Dissection; Drain Site Complication
• Interventions: Other: Suction drain removal

• Registration Number: NCT03971760
• Lead Sponsor: Centre hospitalier de l'Université de Montréal (CHUM)

Brief Summary

A precautionary measure that is frequently used after a neck surgery is the usage of suction drains, which allow the evacuation or air and fluids accumulated at the site of the surgery using negative pressure. Theoretically this helps promote better healing of the wound. Usage of suction drains, however, requires keeping some patients hospitalized after surgery for drain surveillance while they could have otherwise been discharged to safely begin their convalescence at home. In other cases, patient hospitalisation can be prolonged by the usage of suction drains, because surgeons wait for the output of the drain to fall below a certain quantity before removing them. This of course results in additional costs to the health system. The quantity below which the drain output should fall before drain removal is however not something agreed upon in the medical literature and is generally based on a surgeon's personal experience or that of the institution in which they practice. It would be important to better define this value, since prolonged usage of suction drains is not risk-free. Indeed, they constitute, among other things, an access for bacteria to cause an infection to develop inside the neck, which compromises wound healing and may result in more pronounced scarring. This study aims to compare a frequently used output value (30 mL per 24 hours) with a more permissive one of 50 mL per 24 hours. The investigators will look more specifically at wound complications, length of hospitalisation and cost-effectiveness for the health system. This study will recruit patients undergoing neck surgery at the Centre Hospitalier de l'Université de Montréal to compare both of these suction drain output values.

Arm && Interventions

Group	Intervention	Description
Group 1: 30cc/24h	Suction drain removal	This group represents the currently used value of drain output used to determine the timing of drain removal
Group 2: 50cc/24h	Suction drain removal	This group represents the experimental value of drain output used to determine the timing of drain removal

Primary Outcome Measures

Name	Time	Method
Duration of drainage	At the time of patient discharge from the ward, usually up to 1 week	The length of time during which the suction drain is left in place, from the time of the surgery to the time of drain removal

Secondary Outcome Measures

Name	Time	Method
Seroma rate	Up to 6 weeks following surgery	The rate of seroma as wound complication, defined as an accumulation of serous fluid in the surgical space
