Brief Summary
This is a randomized clinical trial with the objective of comparing the time of insertion of two types of perineural catheters in shoulder surgery. These devices are thin lines that have to be inserted over a needle or throw a needle, depending of the type of catheter that is used. The hypothesis is: the installation of Contiplex C or catheter over needle (CON) is faster than a normal contiplex catheter or Catheter throw needle (CTN) at same rate of effectivity.

Outcome Measures
Primary Outcomes (1)
Time of insertion
The time from the insertion of the needle in the skin to: insertion of the catheter and fixation of the tegaderm in the skin
During Procedure
Secondary Outcomes (2)
Visual analogue scale (VAS). 0 (minimum) -10 (maximum) points on VAS scale. Lower scores means less pain and higher scores means more pain.
72 hours to determinate the VAS
Rate of accidental
72 hrs to evaluate the rate of accidental withdrawal
Study Arms (2)
Contiplex C or CON
EXPERIMENTALPatients who will receive a contiplex C block for interscalene nerve block. This catheter also calls Catheter over needle (CON), wich is a catheter that is inserted at the same time that the needle is advancing.
Contiplex or CTN
ACTIVE COMPARATORPatients who will receive a regular contiplex block for interscalene nerve block or also called Catheter throw needle (CTN). This catheter is the gold standard in this centre and the mechanism of insertion is to introduce the catheter throw the needle.
Interventions
This is a catheter used for peripherical nerve block that is inserted at the same time that the needle is being introduced. When the target is achieved, the needle is retired.
This is the traditional catheter used in this centre for peripheric nerve block. In this catheter the needle is introduced first. When the target is achieved the catheter is then introduced throw the needle and after that the needle is retired.
Eligibility Criteria
You may qualify if:
- Patients older than 18 years
- Rotator cuff or proximal humerus surgery
- ASA I-III
- BMI 18-39 kg/m2
- Acceptance of receiving a peripheric nerve block
You may not qualify if:
- Inability to provide consent for the study
- Coagulopathy
- Sepsis
- Severe Renal or hepatic disease (Creatinin \> 2.0 or Child C)
- Allergy to local anesthetics
- Previous peripheral nerve damage
- Refusal of postoperative continuous block technique

- A list of 72 names, corresponding 36 of them to contiplex C and 36 to regular contiplex will be randomized and will be introduced into sealed envelopes. Before, in order to perform the nerve block the anesthesist will open the envelope and will know wich is the catheter he has to use.
