Study Description

Brief Summary:

Background: Anxiety is a common phenomenon in hospitalized patients. In order to reduce it during the surgical procedure, sedatives and anxiolytics are used, which can cause undesirable side effects for patients. Music is described as an effective tool to reduce this anxiety suffered by the patient in the perioperative process.

Objectives: To evaluate the effect of music in patients anxiety and pain during perioperative process in surgical intervention with regional anaesthesia without sedatives or anxiolytics.

Design: A randomized parallel clinical trial study with single-blinded and three harms.

Setting: Operating theater of a public district hospital (serving around 111.000 people) Participants: All patients operated of Total Knee Arthroplasty (TKA) with regional anaesthesia with age between 50 and 85 years old within level I or II of the classification of the American Society of Anaesthesiologists (ASA).

Methods: A total of 81 patients for TKA were randomly assigned to: a control group (headphones without music, without sedation), a sedative group (headphones without music, with sedation) and a experimental group (headphones with music, without sedation). 27 participants for each group. All the participants were using headphones so that it was a single-blinded study. The experimental group were provided with the same music, Piano Guys group. The variables of study were: the pain was measured by vale numerical scale (VNS), the anxiety was measured by the use of State-Trait Anxiety Inventory (STAI), heart rate (HR) variability, blood pressure (BP) variability, saturation of oxygen (Sat02).

Relevance to Clinical Practice: sedation that can causes unwanted side effects by surgical patients can be replaced by music. The music decrease anxiety and pain values in orthopaedic surgery patients.

Detailed Description:

1. Introduction Patients generally experience high levels of anxiety when are hospitalized to undergo surgery and other invasive procedures. Anxiety is an emotional state or condition characterized by stress and unpleasant feelings. Awake patients in the operating theatre are afraid of they will feel pain during the surgical and/or regional anaesthetic procedures, which contributes to increased anxiety. Patients operated under regional anaesthesia are in particular need of sedation during the perioperative period. The purpose of the sedation is to ensure comfort, full cooperation and cardiovascular stability of patients who can maintain a patent airway. However, because of the adverse effects (respiratory depression, nausea, vomiting), optimal patient satisfaction is hard to achieve. Additionally, intraoperative anxiety is often associated with a greater incidence of pain after surgery.

   On the other hand, toxicity of general anaesthetics has been recently studied from its neurotoxic effect to neuroapoptosis. In some cases, they may cause postoperative cognitive dysfunction, and other side effects known as hypoxemia, respiratory depression and increased morbidity and mortality.

   Music has been suggested as a potential intervention to reduce anxiety and pain in the operating room environment. Systematic meta-analysis conducted by Nilsson revealed that 50% of studies (12 of 24) published between January 1995-January 2007 found significant reductions in anxiety scores as measured by STAI. and then more studies have been carried out on the benefits of music, which have continued to show that music reduces preoperative and postoperative anxiety and also reduces postoperative pain.

   There are also studies that conclude that patients to listening music require less midazolam to achieve a similar degree of relaxation as controls in ambulatory surgery patients and that the relaxing music a useful alternative to midazolam for pre-medication before surgery.

   Music holds considerable promise as an adjuvant pain management therapy and in mild cases may be used to supplement, perhaps even replace, pharmaceutical interventions before, during, and after painful procedures. The maximal reduction in pain intensity levels is 0.9 units on a zero to ten scale; although this difference reaches statistical significance, its clinical importance is unclear.

   The aim of this study was to evaluate the effect of the use of music in the perioperative process of patients undergoing surgery of total knee arthroplasty with regional anaesthesia without sedatives and compare anxiety and pain of these patients operated with regional anaesthesia, listening to or not music through headphones in patients without sedation.

2. Material and methods 2.1 Research design and setting This study was a randomized clinical trial study with single-blind, three harms and parallel, that took place in the operating theatre conducted from January 2017 to January 2018.

The participants who had the signed informed consent, once they reached the surgical area, were divided into the three groups according to the randomization list, control group (headphones without music, without sedation), sedation group (headphones without music, with sedation), intervention group (headphones with music, without sedation).

Ninety-five patients were eligible for the purpose of this study and ten were refused to participate in the study. From the 85 remaining subjects, 29 were allocated to the control group, 27 to the sedation group, while 29 were allocated to the intervention group. The CONSORT flow diagram of the progress through the phases of a parallel randomised trial of the three groups is shown on Figure 1.

There were not changes to methods after trial commencement.

2.2 Participants and Sample size The study was performed on participants scheduled for a Total Knee Arthroplasty procedure in a Public Hospital from January 2017 to January 2018. The inclusion criteria were: (1) age with a range from 50 to 85 years old, (2) had regional anaesthesia, (3) duration of surgery not exceeding two hours (4) was willing to participate in the study and signed an informed consent form. The exclusion criteria were: (1) those patients with classification system of American Society of Anaesthesiologists (ASA) 3 or 4, (2) allergic drugs used, (3) psychiatric patients or cognitive issues, (4) patients with whom we have communication problems, (5) patients who for any reason need another type of anaesthesia.

Sample size was determinate regarding the possible differences in the value of numerical pain among the 3 groups studied. Thus, in an analysis of the variance of a three-level factor (ANOVA), assuming a common standard deviation of 1.5 and a minimum difference to detect of 1 point (or equivalent, to detect a difference in any quantitative variable of 0,66 standard deviations), with a statistical power of 80% and an alpha error of 0.05, 53 patients were needed in each of the three groups to detect the difference as statistically significant. A maximum 10% follow-up loss was considered. The result of the sample was 159 participants. An interim analysis was carried out that according to the statistical calculation had to be carried out when arriving at 81 participants (27 for each group). If the result was significant beneficial or harmful compared to the concurrent placebo group the study could be stopped.

2.3 Randomization Randomization lists were generated based on pseudorandom numbers with the SPSS program. For the study, 3 blocks of 81 patients each were performed, corresponding to 27 patients for each group.

All randomization was independent of the researches. Randomization was done by a statistician who was not part of the data analysis.

When a participant was a candidate to participate in the study, the random allocation table was consulted when the group was assigned, the researchers elaborated a closed envelope with information on the intervention received (with or without sedation and with or without music) by the participant in case it was It is necessary to break the simple blind. They were also told to the participants that they would not say whether or not they would listen to music.

The staff, personnel and the assistants to the investigation were blinded to the participants group assignment.

2.4 Intervention Once the participants were included in the study, they were assigned a group according to the randomization table. The participants of the control group were placed with headphones that no produced music and were administered 2 ml of serum, participants in the sedation group were placed with headphones without music and were administered the corresponding dose of midazolam (0.025 mg / kg in patients under 65 years of age. In patients over 65 years of age and / or with hepatic insufficiency or renal insufficiency with glomerular filtration <30 ml / h, the dose of midazolam was 0.015 mg / Kg.) and the participants of the intervention group were placed with headphones that produced music and were administered 2 ml of serum. All the participants were administered the same anaesthetic (levobupivacaine) for regional anaesthesia and the same analgesics in the postoperative period (ropivacaine, dexketeroprofen, paracetamol). A standardization of anaesthesia and analgesia was performed by the anaesthesiology and resuscitation service of the hospital.

The music that the group's patients listened to during their stay in the operating theatre was a collection of songs from the music group Piano Guys, played a volume of 50-55 db. The headphone used were Audio-Technica ATH-M40X and the mp3 was iPod Nano (Apple).

According to some studies, it is recommended that therapeutic music should have a slow tempo, low pitch, regular rhythm, and pleasing harmonics, and should consist of string, flute, and piano selections (Nilsson, 2008; Pelletier, 2004). In a Cochrane review, the genre and the duration of the soothing music did not seem to influence the effectiveness of music intervention.

There were not any changes to trial outcomes after the trial commenced.

2.5 Instruments and Measurements We employed both subjective and objective measures for anxiety and pain in our study.

2.5.1 State-Trait Anxiety Inventory (STAI) The State-Trait Anxiety Inventory (STAI) consists of two different parts, termed STAI-Trait Anxiety Inventory (STAI-TA) and STAI-State Anxiety Inventory (STAI-SA). This test requires patients to complete a 40-item, 20 items measuring state anxiety and 20 items measuring trait anxiety (Spielberger et al.,1970) adding each one of the items of each subscale. The score can range between 0 and 60, representing the highest and lowest levels of anxiety, respectively. In our study, STAI-TA test results were evaluated preoperatively. The STAI-SA was performed during the waiting room (Orthopaedic unit, 30 minutes before surgery) and postoperative period in Post anaesthesia care unit (PACU) (recovery period, 30 minutes after surgery). There are no cut points, but direct scores are transformed into centiles based on sex and age.

2.5.2 Vale Numerical Scale (VNS) Pain intensity is frequently measured for visual analogue scale (VAS) or numerical ranting scale (NRS). We used the NRS, pain was assessed on a 10-point pain intensity numerical rating scale, where 0=no pain and 10=worst possible pain (Lee et al.2015). The researcher gave oral instruction of ''Please said the point at the number to show how much pain do you have right now''. The pain was measured in preoperative, intraoperative and postoperative phase.

2.5.3 Hemodynamic constants: To measure HR and BP, the researchers placed the sensor on the radial area of the patient's forearm for 15 minutes. Monitoring of the electrocardiogram (ECG) and capillary oxygen saturation (SatO2) was continuous. The participants were asked not to move around to ensure the quality of the readings. In our study, HR, BP and SatO2 was measured by a Datex Ohmeda TYPE D-LCC15..03.

2.6 Data collection process This research was approved by the Ethical Committee for Clinical Research, (approved code: PR218/16).

The researchers (SR, MR) checked the operating schedule and met potential participants in the room of orthopaedic unit where we take the signed consent and we gave them the STAI questionnaire.

When the participants reached preoperative area, the researchers looked the group that belonged to each participant according to randomization list and they were monitored hemodynamic constants (HR, BP, SatO2), the headphones were placed with or without music and the dose of sedation or physiological serum (placebo) was administrated according to the study group to which they belonged. The dose of sedation or serum was repeated every 45 minutes until surgery was finished. All the data (STAI preoperative and postoperative, VNS preoperative and postoperative, hemodynamic constants every 15 minutes, dose anaesthetics and analgesics, sociodemographic variables) were registered in a graph created by researchers.

The data collection in each phase, preoperative, intraoperative and postoperative, was carried out by nurses who did not belong to the research team, who were educated before starting the study so that there were no biases in the collection.

2.7 Statistical analysis Categorical variables were described by means of the number of cases, the percentage with respect to the total by category and the number of available data. Continuous variables were described by means of the number of cases, the mean and the standard deviation or the median and the inter-quartile range (IQR). Continuous variables were compared using Student's t-test or Mann-Whitney U-test as appropriate. Fisher's exact test or Pearson's χ2 test were applied to assess the relationship between categorical variables. In order to evaluate the main objective, a covariance analysis was performed to evaluate the role of the intervention in the change in the value of the final pain compared to initial pain. The effects of each intervention were compared by pairs with the adjustment for multiple comparisons of Tukey. The rest of the study variables (STAI questionnaire and hemodynamic constants (BP, HR, SatO2)) were analysed similarly. Models were replicated adjusted by age and gender. Analyses were performed with R software 3.4.0. The statistical significance was set at a probability level <0.05.

2.8 Ethical considerations The participants who met the inclusion criteria were informed by the researchers and they were also given an informative document of the study. The participants who wanted to participate in the study signed an informed consent.

4.1 Limitations When we performed the post-STAI test in the Post Anesthesia Care Unit (PACU), some patients could not read the questionnaire because they did not have the glasses, so the nurse had to ask the questions. In future studies, a better research design or a more suitable testing location can provide a better understanding on this subject. Additional research could examine the effectiveness of listening to preferred music, the use of music as an alternative to another type of sedative drug such as propofol, for other surgical patients, as well as their satisfaction.
