“…] ence and anecdotal reports indicate that fluid leaks in CAPD patients and hernia ruptures occur after bouts of severe coughing [11,12]. In the general population, her nias frequently develop in persons with chronic cough ing, prolonged straining and recurrent weight lifting [13].…”

“…[5][6][7][8][9][10]13,14] and in CAPD patients only during the relaxed state with varying volumes of dialysis solution in the peritoneal cavity [1][2][3][4], The alteration in intraabdominal pressure during coughing, a maneuver frequently recommended to patients during the immedi ate postoperative period, has attracted little attention. We are aware of only one report on intraabdominal pressure during coughing in patients after abdominal surgery [15].…”

Intraabdominal pressures were measured during natural activities in 6 men, age 24–62 years, treated with continuous ambulatory peritoneal dialysis. The pressures were measured with a pressure transducer secured at the level of the umbilicus in the supine, sitting, and upright positions with 0–3 liters intraperitoneal fluid during talking, coughing, straining, changing position, walking, jogging, exercycling, jumping and weight lifting. Coughing and straining generated the highest intraabdominal pressures in every position. The pressures with weight lifting were proportional to the magnitude of the weight lifted up to 50 lbs, but were lower than those during coughing and straining. The pressures were generally higher with greater intraabdominal fluid volumes, especially with jumping and coughing. Exercycling was associated with lower intraabdominal pressure than was jogging, and the pressures were only minimally influenced by intraperitoneal fluid volumes. The results of this study can be used as a guide in establishing preventive measures in patients with intraperitoneal fluid to decrease complication rates related to raised intraabdominal pressures such as dialysate leaks, hernias and hemorrhoids.

“…The abdomen forms the compression system of the cantilever during lifting: raised intra-abdominal pressure produces an air cushion supporting the spine. Davis [1959] found that compared to the erect posture, intra-abdominal pressure was increased in the stooping position and depended on the speed of lift. Inguinal hernias can be produced or complicated by much heavy lifting even if this is done correctly from the orthopaedic aspect.…”

“…Davis [1959] found that intra-abdominal pressure was increased in the stooping position rather than in the erect posture and depended on the speed of``lift''. Palumbo et al [1963] theorized that a shift in the visceral weight from the center of the abdomen to the groin could cause the rupture.…”

“…A gradual increase in intra-abdominal pressure has been found during sustained lifting, reaching levels around 20 mmHg when the subjects were exhausted after around 8 minutes (64). Intra-abdominal pressures >100 mmHg have been measured during heavy lifting in a stooping position, especially during rapid lifts (65), and intra-abdominal pressures around 120 mmHg have been measured during lifting for a few seconds using maximal force (66). Sudden trunk loading during simulated patient handling situations where the patient fell resulted in peak intra-abdominal pressures of 153 mmHg and 120 mmHg among well-trained men and women, respectively (67).…”

Risk and prognosis of inguinal hernia in relation to occupational mechanical exposures -a systematic review of the epidemiologic evidence by Svendsen SW, Frost P, Vad MV, Andersen JH -One in four men undergoes inguinal hernia repair that carries a risk of recurrence and persistent pain. -Occupational mechanical exposures may increase the risk of occurrence and of an unfavourable prognosis. -The epidemiologic evidence is too limited to draw conclusions for or against any causal or prognostic associations. -There is a need for new knowledge with an emphasis on prevention. Scand J Work Environ Health. 2013;39(1):5-26. doi:10.5271/sjweh.3305 Risk and prognosis of inguinal hernia in relation to occupational mechanical exposures -a systematic review of the epidemiologic evidence Objectives The aim of this review was to evaluate the epidemiologic evidence for (i) a causal effect of occupational mechanical exposures on incidence of inguinal hernia, and (ii) a prognostic effect of such exposures on hernia recurrence and persistent pain after inguinal hernia repair. Affiliation MethodsWe performed a literature search in Medline, Embase, and Web of Science up to 3 November 2011.Central information was extracted from included studies, and strengths and limitations were discussed. ResultsAll 23 included studies focused on effects of (work) activities that hardly reflected specific occupational risk factors. Eight studies provided information on risk by occupation or occupational activities. Increased risk was reported in six studies, but inflationary bias was likely. The negative findings in two studies might well be explained by bias towards the null due to crude exposure and/or outcome assessment. Three studies on single strenuous events primarily reflected patients' beliefs regarding risk factors. Information on prognosis with respect to recurrence was found in seven studies. The studies used crude exposure assessment, and two were also underpowered. Four suggested an increased risk. Six studies on prognosis with respect to persistent pain (one of which also concerned recurrence) were practically non-informative for the purpose of this review. ConclusionsThere is insufficient epidemiologic evidence to draw meaningful conclusions about (i) the existence of causal associations between specific occupational mechanical exposures and the development of inguinal hernia, and (ii) the influence of these exposures on prognosis after inguinal hernia repair with respect to hernia recurrence and persistent pain.
