Abstract
Previously we have demonstrated that light can be used to control the release of insulin in diabetic animals, followed by a reduction in blood glucose. This is accomplished using a photoactivated depot (PAD) of insulin injected into the skin, and irradiated by a small external LED light source. In this work for the first time we demonstrate dose-response, showing that we can vary insulin release and commensurate blood glucose reduction by varying the amount of light administered. In addition to demonstrating dose-response, we have shown multi-day depot response, with insulin being released on two different days from the same depot. The material used in these studies was CD-insulin, a form of insulin that has a highly non-polar cyclododecyl group attached, markedly reducing the solubility of the modified material, and allowing it to form a depot upon injection. Upon photolysis, the cyclododecyl group is removed, releasing fully native, soluble insulin. Variable response and multi-day response as demonstrated strongly support the potential utility of the PAD approach for the variable and extended release of therapeutic peptides.

Abstract
BACKGROUND Since the 1950s a small number of centres have used sterile water injections (SWI) to treat renal colic pain. We undertook this review to determine the efficacy of SWI to manage the pain of renal colic. METHODS We searched the electronic databases PubMed, Cochrane Central Register, CINAHL, and Scopus from database inception to 7 November 2021 for randomized controlled trials that met the inclusion criteria. RESULTS Six trials were included in the review (n = 894 patients). Two placebo controlled trials were included in the meta-analysis. Other trials compared SWI to Diclofenac, Morphine, or oral Paracetamol. The overall quality of the trial was low. Compared to a placebo SWI demonstrated a significant reduction in self-reported pain at 30 min (Mean difference [MD] = -4.68, 95% Confidence Interval [CI] = -5.21, -4.15. p < 0.001, I2 = 0%) and at or beyond 60 min post-injection (MD = -5.34 95% CI = -5.85, -4.82, p ≤ 0.001, I2 = 0%). Pain relief provided by SWI was significantly better than oral paracetamol and equivalent to Diclofenac and Morphine. No significant side-effects were attributed to SWI use in any trials. DISCUSSION/CONCLUSION SWI could be a suitable alternative for management of renal colic pain where alternatives such as non-steroidal anti-inflammatory and opioid drugs are either unavailable or contraindicated. However, further research is required to establish the role of SWI in renal colic pain management.

Effect of topical local anaesthesia on injection pain associated with administration of sterile water injections - a randomized controlled trial. BMC Anesthesiol 2022; 22:35. [PMID: 35105307 PMCID: PMC8805377 DOI: 10.1186/s12871-022-01573-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 01/10/2022] [Indexed: 12/18/2022] Open
Abstract
Background Sterile water injections can provide effective pain relief during childbirth, particularly for low back pain related to childbirth. However, the pain associated administering the injections can negatively impact women’s impressions of the procedure. It may discourage women from considering repeat doses despite the quality of analgesia experienced. Determining strategies to reduce the pain related to the administration of sterile water injections would improve the acceptability of the technique. Therefore, the aim of this study was to evaluate the effect of topical local anesthesia on the pain associated with administration of sterile water injections. Methods The study was designed as a multi-arm single-blind, randomized, controlled trial and 120 female healthy students were randomly divided according to one of four groups. The Intervention group received sterile water injections with topical local anesthesia. Control group 1 received sterile water injections without topical local anesthesia, control group 2 received injections of isotonic saline 0.9% with topical local anesthesia and control group 3 received injections of isotonic saline 0.9% without topical local anesthesia. Pain Immediately after the injections and subsidence in pain were recorded using a visual analogue scale. Sensations in the injection area were reported 15 min and the day after the injections. Results The main finding of this study was that local anesthesia with EMLA® reduces the pain associated with the administration of intracutaneous sterile water injections. There was a significant difference in the self-assessed pain score immediately following the injections between the control (73.3 mm) and intervention groups (50.0 mm), p = 0.001. No adverse side effects were reported. Conclusion Local anesthesia with EMLA® reduces the pain associated with intracutaneous administration of sterile water injections. Trial registration The study was registered 08/07/2014 at ClinicalTrials.gov Identifier: NCT02213185.

The Safety and Effect of Local Botulinumtoxin A Injections for Long-Term Management of Chronic Pain in Post-Herpetic Neuralgia: Literature Review and Cases Report Treated with Incobotulinumtoxin A. J Pers Med 2021; 11:jpm11080758. [PMID: 34442402 PMCID: PMC8400134 DOI: 10.3390/jpm11080758] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Revised: 07/25/2021] [Accepted: 07/28/2021] [Indexed: 11/29/2022] Open
Abstract
There are few reports on the safety and effectiveness of long-term botulinumtoxin A (BoNT A) therapy in severe chronic pain of post-herpetic neuralgia (PHN). The literature was searched with the term “neuropathic pain” and “botulinum” on PubMed (up to 29 February 2020). Pain was assessed with the Visual Analogue Scale (VAS) before and after BoNT A therapy. A total of 10 clinical trials and six case reports including 251 patients with PHN were presented. They showed that BoNT A therapy had significant pain reduction (up to 30–50%) and improvement in quality of life. The effect duration seems to be correlated with BoNT A doses injected per injection site. Intervals between BoNT A injections were 10–14 weeks. No adverse events were reported in cases and clinical studies, even in the two pregnant women, whose babies were healthy. The repeated (≥6 times) intra/subcutaneous injections of incobotulinumtoxin A (Xeomin®, Merz Pharmaceuticals, Germany) over the two years of our three cases showed marked pain reduction and no adverse events. Adjunctive local BoNT A injection is a promising option for severe PHN, as a safe and effective therapy in long-term management for chronic neuropathic pain. Its effect size and -duration seem to be depended on the dose of BoNT A injected per each point.

Abstract
BACKGROUND The aim of this study was to investigate if intramuscular injection of sterile water can be used as a human experimental pain model that resembles clinical craniofacial muscle pain and to analyse if the effects differ between sexes. METHODS This randomised, double-blind, placebo-controlled cross-over study included 30 healthy age-matched women and men (23.6 ± 2.4 years). At three sessions, with at least one week of washout in between, 0.2 mL of either sterile water (test-substance), hypertonic saline (58.5 mg/mL; active control) or isotonic saline (0.9 mg/mL; passive control) was randomly injected into the right masseter muscle. Pain intensity (VAS) was continuously assessed during 5 min whereafter pain duration (s) and pain area (au) were calculated; pressure pain thresholds (PPT;kPa) were recorded every 5 minutes during 30 minutes. RESULTS Sterile water evoked pain of similar intensity (74.5 ± 49.9) as hypertonic saline (74.0 ± 50.5); whereas, isotonic saline evoked low-intensity pain (11.4 ± 23.4). The pain induced by sterile water and hypertonic saline had higher intensity (P < 0.001), longer duration (P < 0.001) and larger pain area (P < 0.001) than isotonic saline. There were no significant differences in any pain variable between sterile water and hypertonic saline. The PPT did not change significantly after any substance, except for in women 5 minutes after sterile water injection (P < 0.002). Pain duration was longer in the men for all substances (P < 0.006), while the pain area was larger in women after injection of hypertonic saline (P < 0.003). CONCLUSION These results indicate that pain evoked by sterile water resembles clinical muscle pain and may offer a novel and simpler alternative to hypertonic saline injections.

Abstract
AIM Low back pain (LBP) is a common musculoskeletal complaint among emergency department (ED) admissions. In this study, it was aimed to compare the effectiveness of systemic treatment with intradermal sterile water injection (ISWI) treatment protocol combined with systemic therapy in patients with LBP of unclear chronicity. METHODS A prospective randomized, unblinded, controlled clinical study was conducted on patients admitted to the ED for LBP of unclear chronicity. One hundred twelve patients were randomly assigned to two groups; Group ISWI (n = 56) administered ISWI in the LBP region of patients along with systemic intravenous dexketoprofen therapy, while the other group (n = 56) received only systemic intravenous dexketoprofen therapy. The treatment methods' effectiveness was compared by measuring the pain intensity with the Visual Analog Scale (VAS) at admission, 10th minutes, 20th minutes, 30th minutes, and 24 h later. Also, opioid and analgesic consumptions in 24 h after treatment and patient satisfactions were compared. RESULTS In the treatment of LBP, ISWI treatment was found to be more effective in relieving pain than systemic therapy alone (p < 0.001). Also, it was observed that opioid consumption in the ED and analgesic consumption within 24 h after treatments were decreased in the ISWI group (p < 0.001). The patient satisfaction in the ED was statistically increased (p < 0.001). DISCUSSION In this unblinded study, ISWI with systemic therapy improved pain outcomes more than systemic therapy alone. Further research is needed to determine whether this was due entirely to placebo effect.

Abstract
Background The labor pain is one of the factors encouraging pregnant women for cesarean section delivery. Recently, intradermal and subdermal injection of distilled water has shown to be effective in improving this pain. Objectives The present study aimed to determine which method has a greater impact on labor pain reduction. Methods In this double-blind, randomized clinical trial, 121 nulliparous women with a gestational age of ≥ 37 weeks were randomly divided into three groups: (1) 0.5 cc sterile water injection subdermally at four sacral points with insulin needles (n = 40); (2) 0.5 cc sterile water injection intradermally (n = 39); and (3) needle contact with the mentioned points as the placebo (n = 42). Before the intervention, the VAS score was measured for labor pain, and it was repeated 10, 30, 60, and 90 min after the intervention. The results were compared between the three groups. Results Before the intervention, the mean VAS pain score had no significant difference between the three groups. However, 30, 60, and 90 min after the intervention, the mean pain score was significantly lower in the intradermal and subdermal injection groups than in the control group (P = 0.001); however, the difference between the intradermal and subdermal injection groups was not significant. Conclusions The injection of distilled water by either intradermal or subdermal method was associated with a significant reduction in the pain score during labor, but there was no difference between these two methods in terms of decreasing labor pain. As sterile water injection is a safe, effective, and low-cost method, it is proposed to increase the knowledge of midwives and obstetricians about this method.

Abstract
AIM The aims of this prospective study were to determine the dimension of adherence in rheumatoid arthritis (RA) patients receiving subcutaneously administered anti-tumor necrosis factor-α (anti-TNFα) agents and to evaluate the influence of injection site pain and skin perceptions following subcutaneous administration of anti-TNFα drugs on patients' adherence. METHOD An inception cohort of patients starting subcutaneously administered anti-TNFα treatment was enrolled. Injection site pain perception was assessed through the Self-Injection Assessment Pain Questionnaire (SIAPQ), and adherence to treatment was ascertained by the Compliance Questionnaire for Rheumatology (CQR5). Associations between beliefs and non-adherence, and the influence of demographic (age, disease duration, educational level), clinical (body mass index, patient global assessment, physician global assessment, Numerical Rating Scale of pain, Health Assessment Questionnaire-Disability Index, Simplified Disease Activity Index, and comorbidities measured by the modified Rheumatic Disease Comorbidty Index), and radiographic (Simple Erosion Narrowing Score) variables were assessed using logistic regression models. RESULTS Adherence data over a 12-month interval were available for 193 patients. Of these, 21.7% reported non-adherence to anti-TNFα therapy. No difference (P = .383) was found for anti-TNFα drugs (adalimumab, etanercept, certolizumab pegol and golimumab). In the logistic model, age (P = .0029), higher disease activity (P = .020), low numbers of comorbidity conditions (P = .0004), injection site pain and skin perception (P = .0008), were significantly associated with increased likelihood of medication adherence. CONCLUSION Adherence is influenced by both demographic characteristics (age) and clinical factors (disease activity, comorbidity burden and injection site pain and skin perception) in RA patients.

Abstract
BACKGROUND Normal vaginal delivery is considered a painful process and it is difficult to tolerate the pain. The goal of this study was to compare the effect of injection of sterile distilled water and normal saline on pain intensity in nulliparous women. MATERIALS AND METHODS This triple-blind clinical trial was conducted on 164 nulliparous women randomly selected from among those who were hospitalized in Motahari Hospital of Jahrom, Iran, from 1 May 2012 to 1 October 2013. Women with a gestational age of 37-42 weeks, dilatation of 4-6 cm, and delivery 180 min after the intervention were selected. The subjects were randomly allocated to four groups of intracutaneous and subcutaneous sterile water and normal saline injections. Pain severity was measured 5 min before the injection and every 30 min up to 3 h after the injection using a visual analog scale. The data were analyzed using Chi-square, Scheffe, and Spearman's correlation tests in SPSS software. RESULTS There was no significant difference among the four studied groups concerning gestational age and other demographic characteristics. Chi-square test showed lower pain intensity 120 min after the injection in group 4 (subcutaneous injection of normal saline) (F 3 = 14.75, p < 0.001) and 150 min after the injection in group 3 (intracutaneous injection of normal saline) (F 3 = 14.75, p < 0.001). Chi-square test showed that the duration of the second stage of labor was shorter in group 4 participants (subcutaneous injection of normal saline) (F 3 = -12.23, p < 0.001). CONCLUSIONS The study showed that subcutaneous and intracutaneous injection of normal saline reduced the intensity of pain during childbirth.

Abstract
INTRODUCTION The aim of this study was to investigate the effect of a lower dose subcutaneous sterile water injection technique versus subcutaneous saline injection, on the relief of low-back pain for women during childbirth, and to explore the lasting effects of pain relief after administration (followed at 15, 30, 45, 90 and 120 minutes). METHODS A prospective randomized controlled single-blinded study was conducted, with trial registration (NCT02813330). Women received one-time injections (sterile water or saline) and the effectiveness was observed at 15, 30, 45, 90 and 120 minutes after the intervention. RESULTS The intervention group had statistically significant pain reduction. Assessment of subsequent pain, followed at 30, 45, 90 and 120 minutes, reflected an increasing change with a statistically significant difference. The intervention group had more burning sensations than the control group with a statistically significant difference. CONCLUSIONS The modified technique of double injections of subcutaneous ‘water/ saline’ resulted in significant relief of low-back pain during childbirth.

Abstract
BACKGROUND About 30% of women in labour suffer from lower back pain. Studies of sterile water injections for management of low back pain have consistently shown this approach to be effective. The objective of this evidence-based guide is to facilitate the clinical use of sterile water injections to relieve lower back pain in labouring women. METHODS To identify relevant publications our search strategy was based on computerised literature searches in scientific databases. The methodological quality of each study was assessed using the modified version of the Jadad scale, 12 studies were included. FINDINGS Recommendations regarding the clinical use of sterile water injections for pain relief in labour are reported in terms of the location of injection administration, various injection techniques, number of injections used, amount of sterile water in each injection and adverse effects. DISCUSSION Both injection techniques provide good pain relief for lower back pain during labour. The subcutaneous injection technique is possibly less painful than the intracutaneous technique administered, but we are unsure if this impacts on effectiveness. The effect seems to be related to the number of injections and the amount of sterile water in each injection. CONCLUSION The recommendation at present, based on the current state of knowledge, is to give four injections. Notwithstanding the differences in injection technique and number of injections the method appears to provide significant levels of pain relief and can be repeated as often as required with no adverse effect (apart from the administration pain) on the woman or her foetus.

Abstract
Analgesia and coping with labor pain can prevent suffering during childbirth. Nonpharmacologic methods help women manage labor pain. Strong evidence is available for the efficacy of continuous one-to-one support from a woman trained to provide nonmedical care during labor, immersion in warm water during first-stage labor, and sterile water injected intracutaneously or subcutaneously at locations near a woman's lumbosacral spine to reduce back-labor pain. Sterile water injections also reduce the incidence of cesarean deliveries. Nitrous oxide labor analgesia is not potent, but helps women relax, gives them a sense of control, and reduces and distracts their perception of pain. It is inexpensive; can be administered and discontinued safely, simply, and quickly; has no adverse effects on the normal physiology and progress of labor; and does not require intensive monitoring or co-interventions. Parenteral opioids provide mild-to-moderate labor pain relief, but cause side effects. Although observational studies have found associations between maternal use of opioids and neonatal complications, little higher level evidence is available except that meperidine is associated with low Apgar scores. Patient-controlled intravenous administration of remifentanil provides better analgesia and satisfaction than other opioids, but can cause severe side effects; continuous monitoring of arterial oxygen saturation, anesthesia supervision, one-to-one nursing, and availability of oxygen are recommended. The demand for inexpensive, simple, safe but effective labor pain management for women will undoubtedly increase in places that lack wide access to it now.

Abstract
BACKGROUND Up to one-third of labouring women will experience painful 'back labour'. Sterile water injected lateral to the lumbosacral spine is a simple and well-researched approach to this pain. OBJECTIVE To determine if sterile water injection for low back pain compared to placebo or alternative therapy increased or decreased the rate of Caesarean section. SEARCH STRATEGY We performed a literature search with no language restriction in four databases: the Cochrane library, EMBASE (1980-2009), Ovid Medline (1950-2009) and CINAHL (1982-2009). SELECTION CRITERIA We included all randomised controlled trials (RCTs) of sterile water injection for labour pain that included outcomes of interest and original data. DATA COLLECTION AND ANALYSIS We compared Caesarean section rates among women who received sterile water injection in labour with those who received either placebo treatment or another non-pharmacological treatment modality. Other outcomes included pain scores, use of regional analgesia and women's assessment of treatment. We used Revman 5 for the meta-analysis. Data were entered by one reviewer and independently cross-checked. Pooled outcomes were reported as Relative Risk (RR) or Weighted Mean Difference using Mantel-Haenszel fixed-effects model except when the I2 value >50% indicated significant heterogeneity in which case random-effects model was used. MAIN RESULTS We included eight RCTs. The Caesarean section rate was 4.6% in the sterile water injection group and 9.9% in the comparison group (n = 828) (RR 0.51, 95% CI: 0.30, 0.87). CONCLUSION We believe that a large RCT should be mounted to validate our findings regarding the impact of sterile water injections on mode of delivery.

Intradermal sterile water injections for the relief of low back pain in labour -- a systematic review of the literature. Women Birth 2008; 21:157-63. [PMID: 18926789 DOI: 10.1016/j.wombi.2008.08.003] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2008] [Revised: 08/22/2008] [Accepted: 08/26/2008] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To search literature published on the administration of intradermal sterile water injections to women in labour who experience severe low back pain, and to critically evaluate the evidence for therapeutic merit. METHOD A systematic review of six randomised controlled trials from countries including Canada, Denmark, Iran, Sweden and Thailand was conducted. RESULTS Statistically significant findings (p<0.0001) of relief of low back pain in labour lasting from 10 min to 2 h post-administration. CONCLUSION Intradermal injections of sterile water possess powerful analgesic benefits for women experiencing low back pain in labour and their use in this therapeutic setting is justifiable.

Abstract
BACKGROUND Acupuncture and sterile water injections are nonpharmacological pain relief methods used for labor pain in Swedish delivery wards. Their use has changed over time, the reasons for which are unclear, and acupuncture is currently in more common use than sterile water injections. The aim of this study was to elucidate the clinical use of acupuncture and sterile water injections as pain relief and relaxation during childbirth in Sweden. METHODS Twelve hundred questionnaires were sent out to all delivery wards in Sweden. Nine hundred sixty midwives fulfilled the inclusion criteria, and the response rate was 565 (59%). RESULTS Acupuncture was used for both pain relief and relaxation, whereas sterile water injections were used almost exclusively for pain relief. The midwives' own choice of pain relief during childbirth for a possible future delivery was similar to their choice of method in clinical practice. CONCLUSIONS Our study shows that acupuncture was used for both pain relief and relaxation, whereas sterile water injections were used almost exclusively for pain relief. The results also indicate a weakness in midwives' awareness and use of scientific knowledge and general recommendations about these methods.

Abstract
BACKGROUND About 30% of women experience severe continuous low-back pain in labour, but limited options are available to reduce this pain especially in developing countries and remote areas. AIMS To evaluate the efficacy of subcutaneous sterile water injection in reduction of labour pain compared with placebo. METHODS One hundred (100) consecutive patients were enrolled in a double-blind randomised controlled trial. During the first stage of labour with planned normal vaginal delivery, the intervention group (n = 50) received 0.5 mL sterile water injected subcutaneously and the control group (n = 50) received normal saline as a placebo. Pain score was measured before and 10 and 45 min after the injection, using the faces rating scale. MAIN OUTCOME MEASURE Low-back labour pain. RESULTS The two groups were not significantly different regarding maternal age and weight, gestational age, parity and gravidity and degree of effacement. The median pain score was equal in both groups prior to the injection. Pain severity was reduced in both groups after the injection. However, the median pain score in the sterile water group was significantly lower than the placebo group 10 min (P < 0.01), as well as 45 min, after the injection (P < 0.01). CONCLUSION Administering one subcutaneous injection of sterile water in a painful point of the lumbosacral area is effective in reducing low-back pain during labour.

Abstract
OBJECTIVE To identify, survey and review randomized controlled studies of the use of complementary and alternative medicine (CAM) for obstetric treatment or health promotion. METHODS The MEDLINE database was searched to identify randomized controlled trials of CAM treatment and therapies in obstetrics. Studies examining modalities for treatment or improvement of health status were reviewed. RESULTS Fifty-four articles assessing a variety of health modalities met the criteria for inclusion. Acupressure and ginger for prenatal nausea and vomiting, moxibustion for version of breech presentation, sterile water injections for back pain relief in labor, and perineal massage to prevent perineal trauma have three or more studies demonstrating beneficial effect. Other interventions have been studied less, and evidence for them is limited. CONCLUSIONS Some CAM interventions have evidence of effectiveness for use in obstetric patients, while others require further investigation before they can be considered for use in practice.
