[PMID: 38453135 DOI: 10.1016/j.joms.2024.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 02/12/2024] [Accepted: 02/12/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND Postoperative pain and swelling associated with the removal of the third molar (M3) adversely affect the patient's quality of life. PURPOSE The study aims to measure pain reduction and analgesic use in patients treated with pulsed electromagnetic field (PEMF) therapy following M3 removal and compares it to patients who did not receive PEMF. STUDY DESIGN, SETTING, SAMPLE The single-center study was designed as a randomized, prospective, controlled, double-blinded trial on a sample of patients with impacted mandibular M3 ascertained by x-ray orthopantomography and computed tomography. PREDICTOR/EXPOSURE/INDEPENDENT VARIABLES The predictor variable is postoperative pain management. It was assigned randomly to each subject who received either PEMF or standard therapy. MAIN OUTCOME VARIABLES The pain was quantified using a 100 mm visual analog scale and the number of analgesics taken. Each subject kept a daily clinical diary for 7 days, recording the amount of pain using the visual analog scale and the number of analgesic tablets taken. COVARIATES The study covariates were age, sex, tobacco use, and Pell and Gregory's classification of M3s. ANALYSES Student's t test was used, placing the statistical significance for P value < .05. The primary planned analysis was a 2-group, continuity-corrected, χ2 test of equality of proportions. RESULTS The study sample included 90 patients, 47 men and 43 women, with an average age of 32.43 ± 8.80 years. PEMF was statistically associated with improved pain reduction (2.08 vs 5.04 with a P value = .0002) and consumption of fewer analgesics than the control group (2.6 vs 5.8 with a P value = .0062). CONCLUSIONS AND RELEVANCE The study's results attest to the effectiveness of PEMF therapy in pain control after M3 surgery.

[PMID: 38387857 DOI: 10.1016/j.joms.2024.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND The removal of the lower third molar is a routine procedure in oral surgery, yet it often leads to postoperative side effects, particularly inflammation. Despite various interventions explored in prior studies, there is still a need for effective strategies, such as anti-inflammatory substances, to address postoperative side effects. PURPOSE The purpose of this study is to answer the following clinical question: Does the local injection of 0.9 M mannitol reduce postoperative pain, trismus, and swelling in patients undergoing bilateral symmetrically impacted mandibular third molar extraction? STUDY DESIGN, SETTING, SAMPLE This prospective, single-blind, split-mouth study at Hamadan Dental School involved 30 patients with bilateral symmetrically impacted mandibular third molars. Inclusion criteria were: no current medication, no anesthesia allergies, bilateral symmetrically impacted mandibular third molars, non-smokers, and the absence of systemic diseases. Exclusion criteria were: poor oral hygiene, alcohol/cigarette use, drug consumption, diabetes, systemic/gastrointestinal disorders, infection at the surgical site, lack of patient cooperation, and mannitol/anesthetic allergy. PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE The predictor variable was therapeutic injection, and it was grouped into two categories, 0.9 M mannitol solution or distilled water. MAIN OUTCOME VARIABLE The primary outcome variable was pain. Secondary outcomes are trismus, swelling, patient satisfaction, and analgesic consumption. COVARIATES Covariates included demographic information and operative details. ANALYSES Statistical analyses included repeated measures and paired t-tests with a significance level set at P < .05. RESULTS The study comprised 30 participants (mean age: 22.6 ± 3.59 years; 6 men, 24 women). In the test group, pain intensity significantly decreased from 5.30 on surgery day to 0.00, with subsequent values of 2.97, 1.30, 0.40, 0.17, and 0.03. The control group also decreased from 7.68 to 0.00, with values of 4.73, 2.67, 0.97, 0.23, and 0.07. The difference was statistically significant (P < .001). No significant swelling differences at T1, T3, T5, and T7 (P > .05). The intervention group had improved maximum mouth opening at T1, T3, T5, and T7 (P = .011) compared to the control group. CONCLUSION AND RELEVANCE Mannitol infiltration significantly reduces postoperative pain and trismus in impacted third molar surgery. This finding underscores the potential for improved patient comfort and recovery in this context.

THE JOURNAL OF PAIN 2023; 24:1151-1162. [PMID: 36878385 DOI: 10.1016/j.jpain.2023.02.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 02/16/2023] [Accepted: 02/28/2023] [Indexed: 03/07/2023]
Abstract
Peripheral magnetic stimulation (PMS) is a potentially promising modality to help manage postoperative pain. We systematically reviewed the effect of PMS on acute and chronic postoperative pain. MEDLINE, Cochrane CENTRAL, EMBASE, ProQuest Dissertations, and clinical trials.gov were searched from inception until May 2021. We included studies of any study design that included patients ≥18 years of age undergoing any type of surgery that administered PMS within the perioperative period and evaluated postoperative pain. Seventeen randomized controlled trials and 1 nonrandomized clinical trial were included into the review. Thirteen out of the 18 studies found a positive effect with PMS on postoperative pain scores. In our meta-analysis, peripheral magnetic stimulation was more efficacious than sham or no intervention within the first 7 postoperative days (mean difference [MD] -1.64 on a 0 to 10 numerical rating score, 95% confidence interval [CI] -2.08 to -1.20, I2 = 77%, 6 studies, 231 patients). This was also true at 1 and 2 months after surgery (MD -1.82, 95% CI -2.48 to -1.17, I2 = 0%, 3 studies, 104 patients; and MD -1.96, 95% CI -3.67 to -.26, I2 = 84%, 3 studies, 104 patients, respectively). A difference was not seen with persistent pain at 6 and 12-months after surgery, acute postoperative opioid consumption, or adverse events between groups. Results are limited by heterogeneity and generally low-quality studies, as well as low or very low quality of evidence. High-quality and adequately blinded trials are needed to definitively confirm the benefits of peripheral magnetic stimulation administered in the perioperative period. PERSPECTIVE: This review evaluates the efficacy and safety of PMS on postoperative pain. The results help elucidate PMS' role in postoperative pain management and identify gaps where more research is required.

Abstract
Muscle atrophy refers to the deterioration of muscle tissue due to a long-term decrease in muscle function. In the present study, we simulated rectus femoris muscle atrophy experimentally and investigated the effect of pulsed electromagnetic field (PEMF) application on the atrophy development through muscle mass, maximal contraction force, and contraction-relaxation time. A quadriceps tendon rupture with a total tenotomy was created on the rats' hind limbs, inhibiting knee extension for 6 weeks, and this restriction of the movement led to the development of disuse atrophy, while the control group underwent no surgery. The operated and control groups were divided into subgroups according to PEMF application (1.5 mT for 45 days) or no PEMF. All groups were sacrificed after 6 weeks and had their entire rectus femoris removed. To measure the contraction force, the muscles were placed in an organ bath connected to a transducer. As a result of the atrophy, muscle mass and strength were reduced in the operated group, while no muscle mass loss was observed in the operated PEMF group. Furthermore, measurements of single, incomplete and full tetanic contraction force and contraction time (CT) did not change significantly in the operated group that received the PEMF application. The PEMF application prevented atrophy resulting from 6 weeks of immobility, according to the contraction parameters. The effects of PEMF on contraction force and CT provide a basis for further studies in which PEMF is investigated as a noninvasive therapy for disuse atrophy development. © 2022 Bioelectromagnetics Society.

Int J Mol Sci 2022; 23:ijms23105661. [PMID: 35628471 PMCID: PMC9147061 DOI: 10.3390/ijms23105661] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 05/14/2022] [Accepted: 05/17/2022] [Indexed: 12/04/2022] Open
Abstract
Despite advances in medicine, mortality due to sepsis has not decreased. Pulsed electromagnetic field (PEMF) therapy is emerging as an alternative treatment in many inflammation-related diseases. However, there are few studies on the application of PEMF therapy to sepsis. In the current study, we examined the effect of PEMF therapy on a mouse model of lipopolysaccharide (LPS)-induced septic shock. Mice injected with LPS and treated with PEMF showed higher survival rates compared with the LPS group. The increased survival was correlated with decreased levels of pro-inflammatory cytokine mRNA expression and lower serum nitric oxide levels and nitric oxide synthase 2 mRNA expression in the liver compared with the LPS group. In the PEMF + LPS group, there was less organ damage in the liver, lungs, spleen, and kidneys compared to the LPS group. To identify potential gene targets of PEMF treatment, microarray analysis was performed, and the results showed that 136 genes were up-regulated, and 267 genes were down-regulated in the PEMF + LPS group compared to the LPS group. These results suggest that PEMF treatment can dramatically decrease septic shock through the reduction of pro-inflammatory cytokine gene expression. In a clinical setting, PEMF may provide a beneficial effect for patients with bacteria-induced sepsis and reduce septic shock-induced mortality.

Efficacy of adjuvant ozone therapy in reducing postsurgical complications following impacted mandibular third-molar surgery: A systematic review and meta-analysis. J Am Dent Assoc 2021; 152:842-854.e1. [PMID: 34579810 DOI: 10.1016/j.adaj.2021.05.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 05/05/2021] [Accepted: 05/14/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Results from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis. METHODS The authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence. RESULTS Patients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, -3.94 to -1.56) and at 7 days (95% CI, -1.67 to -0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of -0.44 at 24 hours, 0.63 at 72 hours, and -0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, -1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, -0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, -1.34 to 4.18; 4 studies, 133 patients). PRACTICAL IMPLICATIONS Evidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.

Abstract
OBJECTIVES To evaluate the efficacy of pulsed electromagnetic field (PEMF) in relation to reducing postoperative pain, analgesic use, and wound healing in patients undergoing Cesarean section (C-section). METHODS This randomized, double-blind, placebo-controlled trial evaluated 72 women who underwent elective C-section. Thirty-six patients were assigned to the active-PEMF and 36 to the sham-PEMF groups. The participants were asked to report their pain intensity on a Visual Analog Scale (VAS) at 2, 4, 6, 12, and 24 hours and 2, 4, and 7 days after surgery. The amount of analgesics used was recorded. The surgical site was evaluated to assess the wound-healing process on the seventh postoperative day. RESULTS Postoperative pain VAS scores were significantly lower in the active-PEMF group in all the measured periods within the early and the late postoperative periods. Fewer women in the active-PEMF group experienced severe postoperative pain within 24 hours postoperatively (36% vs. 72%, P=0.002). Analgesic use during the first 24 hours after C-section was 1.9-times lower in the active-PEMF group (1.6±0.7 vs. 3.1±1.2, P<0.001). The total analgesic use during the seventh postoperative days was 2.1-times lower in the active-PEMF group than in the sham group (1.7±0.7 vs. 3.7±1.1, P<0.001). Seven days postoperatively, patients in the active-PEMF group had better wound healing with no exudate, erythema, or edema (P=0.02). CONCLUSIONS PEMF treatment after C-section decreases postsurgical pain, analgesic use, and surgical wound exudate and edema significantly, and is associated with a high level of patient satisfaction.
