Trial summary

Postsurgical pain is a relevant side effect following surgery which increases the risk of various complications and delays postoperative patient recovery. Among the many types of surgeries, mastectomy causes not only acute but also chronic pain in many patients. Read more about this study

About this study

Postsurgical pain is a relevant side effect following surgery which increases the risk of various complications and delays postoperative patient recovery. Among the many types of surgeries, mastectomy causes not only acute but also chronic pain in many patients. Therefore, it is important to control pain and increase patients' recovery satisfaction following many kinds of operations by using as small an opioid analgesic dose as possible and adding a nonopioid analgesic to reduce the side effects of narcotic analgesics. Among nonopioid analgesics, lidocaine and magnesium are drawing attention, having been shown to be helpful in controlling postoperative pain by lowering pain hypersensitivity to surgical stimuli. An intraoperative intravenous injection of lidocaine has been reported to improve postoperative pain control by reducing postoperative pain and opioid consumption. Another report showed that an intraoperative intravenous injection of lidocaine improved the quality of postoperative functional recovery after general anesthesia in a laparoscopic cholecystectomy patient. In addition, a review article on the effect of intraoperative intravenous injection of magnesium found it to be an effective analgesic that may be added to conventional opioid-based therapy because it generally reduces opioid consumption, decreases pain assessment for 24 hours after surgery, and lacks severe side effects in relation to magnesium administration. However, there has been insufficient research comparing the intraoperative intravenous injection of lidocaine or magnesium in terms of which is more helpful for general functional recovery and decreased postoperative pain. Recently, the scope of research on anesthesia has come to embrace postanesthetic recovery; to help patients return to daily life, the research trend is now shifting from the improvement or resolution of a specific symptom to the measurement of general recovery. A widely used method to measure postoperative recovery is the Quality of Recovery 40 (QoR-40) survey.

Therefore, in this study, the researchers investigated the intraoperative intravenous injection of lidocaine and the intravenous injection of magnesium to compare these drugs' helpfulness in the functional recovery of mastectomy patients after general anesthesia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LidocaineDrug

    The lidocaine group (Group L)- 1% lidocaine 40 mL is prepared in a 50 mL syringe; A bolus dose of the studied drugs are administered for 15 minutes immediately after a subject is brought into the operating room, and the vital signs are checked (from the beginning of anesthesia induction). Subsequently, an intravenous injection of the maintenance dose is continuously performed and later stopped just before transferring the subject to a recovery room. (Group L subjects are administered lidocaine 2 mg/kg for 15 minutes immediately after the anesthesia induction, and then lidocaine 2 mg/kg/h is continuously injected. The dose of lidocaine and magnesium in this study has been shown in previous studies to be safe and to have an analgesic effect.)

  • Magnesium SulfateDrug

    the magnesium group (Group M)- MgSO4 4g 40 mL is prepared in a 50 mL syringe.) A bolus dose of the studied drugs are administered for 15 minutes immediately after a subject is brought into the operating room, and the vital signs are checked (from the beginning of anesthesia induction). Subsequently, an intravenous injection of the maintenance dose is continuously performed and later stopped just before transferring the subject to a recovery room. The dose of magnesium in this study has been shown in previous studies to be safe and to have an analgesic effect.

  • SalineDrug

    the control group (Group C) - 0.9% normal saline 40 mL is prepared in a 50 cc syringe. A bolus dose of the studied drugs are administered for 15 minutes immediately after a subject is brought into the operating room, and the vital signs are checked (from the beginning of anesthesia induction). Subsequently, an intravenous injection of the maintenance dose is continuously performed and later stopped just before transferring the subject to a recovery room.Group C subjects are administered the same dose of normal saline.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The difference of QoR-40 global scores

    The investigators will evaluate the quality of recovery after general anesthesia by considering the global score (200 points in total) of QoR-40 surveys, which is obtained by summing the subtotal scores for emotional status, physical comfort, psychological support, physical independence, and pain. The QoR-40 administered 24 hours after the operation is the primary endpoint of this research.

    Measured: 24 hours after mastectomy

Questions about this trial

What is this clinical trial studying?

A study testing Lidocaine, Magnesium Sulfate and Saline in people with Breast Cancer, run by Yonsei University at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The difference of QoR-40 global scores (time frame: 24 hours after mastectomy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2015.
